Unit I: 

Minor Experiment

a) Titration of strong/weak acid against NaOH pHmetrically.

b) Determine the dissociation constant of a weak acid.

c) Determine the solubility and solubility product of a sparingly soluble salt like BaSO4, or PbSO4 or AgCl in water conductometrically.

d) i) Determination of cell constant of a given cell.

    ii) Determination of specific and equivalent conductance of the given electrolyte (NaCl) at different dilutions.

e) Titration of Strong/weak acid against Strong/weak base conductometrically

Major Experiment

a) First Order Kinetics- To determine the specific reaction rate of the hydrolysis of methyl acetate/ethyl acetate catalyzed by hydrogen ions at room temperature.

b) Second Order Kinetics- Saponification of ethyl acetate.

c) To study the effect of acid strength on the hydrolysis of an ester.

d) To study kinetically the reaction rate of decomposition of iodide by H2O2.

e) Titrate a tribasic acid (H3PO4) against a strong base (NaOH).

f) Determine the composition of mixture of HCl and Acetic acid conductometrically using NaOH.
