What is general criteria of choosing a suitable indicator for a given titration?

A

The indicator should have a broad `pH` range.

B

`pH` at the end point of titration should be close of neutral point of indicator

C

The indicator should have neutral point at `pH = 7`.

D

The indicator must show a sharp colour changes near the equivalence point of titration point.

Text Solution

Verified by Experts

The correct Answer is:
B, D
a. Wrong: Indicator should have a small transition range.
b. Correct: `pH` at equivalence point `~~pH_(Ind)`
c. Wrong: `pH` at equivalence point and at the end point may be different.
d. Correct: Factual statement.

What is the role of indicator in titration ?

An acid-base titration consists of the controlled addition of a dissolved base to a dissolved acid (or the reverse). Acid and base react rapidly to neutralize each other. At the equivalence point, equivalents of reacting substances are equal. The pH during a titration changes every time with a drop of titrant added, but the rate of this change varies enormously. A titration curve, graph of pH as a function of the volume of titrant, displays in detail how the pH changes over the course of an acid base titration. Significantly. the pH changes most rapidly near the equivalence point. The exact shape of a titration curve depends on the K_(a) and K_(b) of acid and base The suitable indicator for this titration will be:

Select the correct set of the statements for an acid type indicator used in a titration : (i) In general, pH range of an indicator is (pK_(a)-1) to (pK_(a)+1) and indicator shows its characteristic colours in this range. (ii) In general pH range of an indicator is (pK_(a)-1) to (pK_(a)-1) and indicator does not show its characteristic colours in this range (iii) In this relation : pH=pK_(In) +log_(10)((["In"^(-)])/(["HIn"])),pH value representes pH of indicator solution. (iv) In this relation : pH=pK_(In) +log_(10)((["In"^(-)])/(["HIn"])),pH value represents pH of resulting solution containing indiactor .
