Once the students step into the senior secondary, they are expected to devote all their time and attention to studies, for this stage is considered as the most crucial stage of their lives. Performance and inclination for a particular student at this stage will decide his/her future. It is a well-known fact that most students aspire to pursue their higher studies in science. Chemistry is probably the most sought after discipline in science. It is indeed a matter of immense prestige to study in the department of chemistry in any esteemed college or university.
The aim of SSC chemistry is precise to coach students for any examination that would come their way. The syllabus is thus, designed in a fashion which inculcates in the students not just the basics of general chemistry but also strengthens their foundation as a whole.
The SSC chemistry syllabus entails a large number of topics like the molecular structure, chemical structure, atomic theory, acids and bases, the periodic table, chemical reactions, all about hydrogen and hydrocarbons, organic and inorganic chemistry, redox reaction, states of matter, etc. The chemistry course is more or less similar under all the boards across the country except for some minimal variation.
All You Need To Know About Chemical Analysis
Here we aim to discuss chemical analysis in a way which could aid you to understand the topic in the easiest way possible. Chemical analysis pertains to that branch of chemistry which we call analytical chemistry. Therefore, let us briefly take a look at analytical chemistry.
An Introduction To Analytical Chemistry
Analytical chemistry is the study and practice of methods by which matter is identified, separated and quantified. There are further two classes of the branch:
- The qualitative analysis studies the composition of compounds. It generally detects ions in an aqueous solution, and thus the materials which have to be examined must be brought to this state for the procedure to take place.
- The quantitative analysis is concerned with matter’s numerical amount.
Chemical analysis is done by the use of various methods which includes both wet chemical methods and instrumental methods which is the modern way. The wet chemical methods analyze the matter in its liquid phase. They largely depend on the chemical reaction for analysis to take place. The chemical reaction takes place between the analyte and a reagent. This type of analysis is used for less complex matters.
The instrumental methods involve the employment of instruments to analyze the chemical properties of matter. Most of the chemical analysis falls under this category. Unlike wet chemical analysis, it does not use a balance but various other instruments. It can either be used to determine the characteristics of a matter or a chemical reaction that takes place between an analyte and a reagent. It is further divided into the gravimetric and volumetric analysis. The 18th-century Swedish scientist Torbern Bergman is the founder of quantitative chemical analysis.
Chemical analysis is done to determine both chemical properties or chemical composition of matter. An elaborate and intricate procedure is required for these purposes. These procedures have been evolving continuously. Scientists are constantly engaged in looking for better ways to go about the field of chemical analysis. They are trying to combine classical methods with their innovations to give yield to an even better procedure.
Jons Jacob Berzelius who was a professor of chemistry at the Karolinska Institute in Sweden is widely considered one of the fathers of modern chemistry. His insights have influenced and inspired chemists through ages. He is noted for his contribution to classical analytical techniques and his further study into isomers and catalysts.
Stages Of Chemical Analysis
The following steps are involved in chemical analysis-
- The first step involves sampling in which a slight portion is removed from the whole body for examination.
- The second step is the preparation of the sample. It is then treated either physically or chemically. For example, natural water samples which are to be examined for dissolved oxygen are placed in air-tight containers and stored in a refrigerator.
- This step is the main step which incorporates all the laboratory treatment, assessment and calculations. Sometimes many samples are simply put together into a homogenous sample and then assayed.
- After the completion of assays, the results are mathematically transformed into a comprehensive manner. Then an average is calculated to eliminate error from the estimated correct result. Accuracy is the agreement in the degree between the true value and experimental results. Every result has a number of random errors, these are tiny fluctuations which may be minimized but not completely annihilated.
Though chemistry analysis may seem a little complicated in the beginning, with time and patience students grasp it very well. It is an intricate part of the SSC chemistry syllabus and is one of the most important chemistry topics and must be studied well. The senior secondary is a very important phase for a student.
If you wish to become an analytical chemist or undertake analytical chemistry for your undergraduate studies or undergraduate research. It is mandatory for you to master this topic right from its roots and there is no better time to begin than now. If you wish to pass your SSC examination brilliantly, you must focus on the courses that make up your syllabus.
Although chemical analysis is a little more complicated than other topics like the table of elements, molecular formula, basic chemistry and biochemistry or atoms and molecules, do not give up hope quickly. Invest your labour and you shall not be deprived of its fruit.
School is never enough for a student to get the best out of himself. The extremely low teacher-student ratio and lack of sufficient time often leave students in a state of confusion which leads to irrevocable damage to the base of their knowledge. Tutors can be of great help to students in times like these.
One is often perplexed as to when to go looking for a teacher for private tuitions. But do not worry as platforms as Superprof provides you with the most eligible teachers for private tuitions. Although there are several other sites, Superprof is the highest rated one with an avalanche of positive feedback.
It is not less tedious for students to travel to far off places for tuition classes right after spending the whole day at school. Superprof allows you to appoint teachers who live close to your house or can travel to your house to conduct classes in the comfort of your home. Contacting private tutors online is the cheapest and fastest way to find one. It is not at all secretive about its applicants’ details. It lays open the qualifications, experiences and feedback from his/her previous appointments. This way it becomes easy for the students or their parents to choose the best-suited candidate. At the SSC level, one cannot afford to waste time on trial and error of private tutors and thus Superprof is the safest bet.
Superprof or other online tutorship is available in almost all cities across the country. Hire a teacher and get all your doubts cleared. A tutor also helps students to brush up their weak points and prepare them for the examination by making them solve past papers, chemistry test questions, multiple-choice questions and also encourage them to take part in competitive exams like the olympiad.
Online Courses And Sites
There are several online sites which have developed an online learning program for students. Eligible teachers upload videos, called e-classes for students to view. Instead of one on one class, they are accessed by numerous students. Since these are in the form of a recorded video, it can be seen a number of times by the students to make their perception crystal clear.
Online chemistry courses are another excellent option for students to understand and revise their chapters. The greatest advantage of this lies in the fact that these courses do not require you to report at a fixed time. The flexibility of the timing is of great convenience for the students. There is a mammoth number of online chemistry topics available on the internet. It ranges from the history of chemistry to various chemistry research, from applied chemistry to nuclear chemistry and much more. Any decent online learning will cover all the topics regulated by the SSC syllabus.
Now that you are somewhat familiar with chemical analysis, try sharpening your skills by reading further about it and solving test papers. An average but diligent student always has the advantage over an exceptional but idle one. A student must always remember that SSC is a step much higher than class 10. He /she will be required to put in much more effort than before. Thus, do not shy away from taking all the help you can. Be it from your school teachers, friends, private tutors or online courses.
