Question

Ostwald's dilution law is not applicable on ? (a) CH OOH 3 (b) NH OH 4 (c) 2 Zn OH ( ) (d) CH COONa​

Answer 1

In the given options, NaCl is strong electrolyte, NaOH is strong base and H

2

SO

4

is strong acid.

Option D CH

3

COOH is weak acid (electrolyte) and is applicable to Ostwald's law.

Answer 2

Answer:

Correct option is D. CH3COONa

Explanation:

Statement : The statement of ostwalds dilution law is only at infinte dilution the weak electrolyte undergoes complete ionization .

This law is applicable for weak electrolytes.

This law is not applicable for strong electrolyte.

As strong electrolytes are those which in completely ionized at all dilution.

There is no any other condition for strong electrolytes hence this law is not applicable for strong electrolyes.

In above option CH3COONa is the strong electrolyte.

In this sodium acetate is salt so it completely dissolved in water so it is a strong electrolyte.

Correct option is D.
