Description

PHARMACEUTICAL ANALYSIS I ACID-BASE TITRATION (Important Questions) 10 marks 1. Explain the different types of acid-base titration with the help of neutralization curves. 2. Discuss in detail the neutralization curves for acid-base titration. Indicate the choice of indicators in each case.

The Choice of indicators based on the type of titration is tabulated below.

Types of titration

Indicators

Strong acidstrong base

Phenolphthalein is usually preferred because of its more easily seen colour change.

Weak acidstrong base

Phenolphthalein is used and change sharply at the equivalence point and would be a good choice.

Strong acidweak base

Methyl orange will change sharply at the equivalence point.

Weak acid-weak base

Neither phenolphthalein, not methyl orange is suitable. No indicator is suitable because it requires a vertical portion of the curve over two pH units.

5 marks 1. Define acid-base indicators. Explain theories of acid-base indicators. 2. Explain the theories of acid-base titration....
