Which of the following is a polyprotic acid? sulfurous acid formic acid chlorous acid

Answer 1

If an anion is behaving an acid then it will form conjugate base by donating its electronsAnd stability of acid anion depends upon the stability of conjugate base .

If conjugate base is stable , then its Kb will be high and thus

An anion will behave as acid depends upon the kb of conjugate base formed.

Option (C) is correct.

2.

Acids which can donate more than one proton or have basicity more than one are called polyprotic acids.

Here H2SO3 i.e. sulfurous acid gives

H2SO3 >>>> 2H^+ and SO3^-2.

Chlorous acid i.e. HClO2 gives only one proton and formic acid HCOOH gives one proton.

So option 1st is correct.
