List of Experiments

Micro-chemical methods are available for several of the practical experiments.
Wherever possible such techniques should be used:

A. Basic Laboratory Techniques
1. Cutting glass tube and glass rod
2. Bending a glass tube
3. Drawing out a glass jet
4. Boring a cork

B. Characterization and Purification of Chemical Substances
1. Determination of melting point of an organic compound.
2. Determination of boiling point of an organic compound.
3. Crystallization of impure sample of any one of the following: Alum, Copper Sulphate, Benzoic Acid.

C. Experiments based on pH
(a) Any one of the following experiments:
• Determination of pH of some solutions obtained from fruit juices, solution of known and
varied concentrations of acids, bases and salts using pH paper or universal indicator.
• Comparing the pH of solutions of strong and weak acids of same concentration.
• Study the pH change in the titration of a strong base using universal indicator.
(b) Study the pH change by common-ion in case of weak acids and weak bases.

D. Chemical Equilibrium
One of the following experiments:
a) Study the shift in equilibrium between ferric ions and thiocyanate ions by increasing/decreasing
the concentration of either of the ions.
b) Study the shift in equilibrium between [Co(H2O)6]2+ and chloride ions by changing the
concentration of either of the ions.

E. Quantitative Estimation
i) Using a chemical balance.
ii) Preparation of standard solution of Oxalic acid.
iii) Determination of strength of a given solution of Sodium Hydroxide by titrating it against
standard solution of Oxalic acid.
iv) Preparation of standard solution of Sodium Carbonate.
v) Determination of strength of a given solution of Hydrochloric acid by titrating it against standard
Sodium Carbonate solution.

F. Qualitative Analysis
(a) Determination of one anion and one cation in a given salt
Cations- Pb2+, Cu2+, Al3+, Fe3+, Mn2+, Ni2+, Zn2+, Co2+, Ca2+, Sr2+,Ba2+, Mg2+
, [NH4]+Anions – [CO3]2-, S2-, [SO3]2-, [SO4]2-, [NO3]-, Cl-,Br-, I-, [PO4]3-, [C2O4]2-, CH3COO-
(Note: Insoluble salts excluded)
(b) Detection of -Nitrogen, Sulphur, Chlorine in organic compounds.
