Question

The "degree of dissociation of sulphurous acid $20\%."$ What is meant by the above statement? Would you classify sulphurous acid as a strong electrolyte or a weak electrolyte?

Answer 1

Step 1 Definition

The degree of dissociation is the proportion of acid molecules that have to dissociate in a given solution.

The degree of dissociation of sulphurous acid in an aqueous solution.

Step 2 Classify the Sulphurous acid and the above statement.

We have given the degree of dissociation of sulphurous acid $20\%.$

That's means every 100 molecules only 20 molecules dissociate into ions.

Sulphurous acid is a weak electrolyte.

Step 3 Final answer

Therefore, the degree of dissociation is less than $30\%$.
