• Practical assessment of STPM Chemistry

7 comments:

thx a lot guru! u helped me a lot.. as my teacher is quite fierce and we cant ask any question if we have any doubt or we don't know how to solve it so my class didn't manage to hand in the report on time twice and we got zero for that 2 experiments. hope u can post more experiment reports especially those hard ones.. THANK YOU!!

nice Chemistry Exepriments

THANK YOU!!!!!

TITRIMETRIC MTHODS Titrimetric methods are widely used in chemistry to determine oxidants, reductants, acids, bases, metal ions, etc. Titration is based on a reaction between the analyte (unknown sample) and the regent of known concentration and reaction stoichiometry. The volume or mass of the reagent needed to react completely with a fixed quantity of the analyte is obtained from which the amount of analyte is determined. Titrimetric methods include powerful group of quantitative procedures that are based on measuring the amount of reagent consumed by the analyte. These methods include, i. Volumetric titrimetry. This involves measuring volume of solution of known concentration that is needed to react completely with the sample. The reagent of exactly known concentration is refered to as standard reagent. Titration is the process in which the standard reagent is added to a solution of the sample until the reaction is judged to be complete. Back titration is the process by which the excess of the standard solution used to consume the sample is determined by titration with a second standard solution. Equivalence point and end-point are confused to mean the same but they are totally different. Equivalence point is a point in titration when the amount of standard solution added is exactly equal to the amount of the sample whereas end-point is the point in titration when a physical change occurs that is associated with a condition of chemical equivalence. The two values are usually different and the difference gives the titration error. Indicators are added to the solution mixtures to produce an observable physical change at the end-point or near equivalence point ii. Gravimetric titrimetry. This involves measuring mass of reagent that reacts completely with the sample. iii. Coulometric titrimetry. Here the reagent is a constant direct electrical current of known magnitude that consumes the sample. Here the time is required, and the total charge to complete the electrochemical reaction

As we know that matter exists in different physical states under different conditions of temperature and pressure. For example solid state, liquid gases plasma and BEC etc. Now we will study about different aspects of solid state.

EXPERIMENTAL LABORATORY MANUAL by discipline GENERAL CHEMISTRY for students of technical specialties, 2015

The study programs for scientific and technical degrees include classroom theoretical teaching, analysis and resolution of real exercises, and some more practical teaching in the laboratory. The laboratory teaching focuses on the application of the theoretical concepts and principles to practical cases, in order to complement the theoretical classes and to reinforce the understandability of the main theoretical concepts.
