Textbook Problem

Order each of the following pairs by acid strength, giving the weaker acid first. Explain your answer.

  1. a HNO3, HNO2
  2. b HCO3, H2CO3
  3. c H2S, H2Te
  4. d HCl, H2S
  5. e H3PO4, H3AsO4

Interpretation Introduction

Interpretation:

The order of weaker acid in the given pair has to be explained.

Concept introduction:

Strong acid:

According to Arrhenius theory, a compound or a substance which completely ionized in a aqueous solution to give a hydronium ion and anion is said to be strong acid.

Strong base:

According to Arrhenius theory, a compound or a substance which completely ionized in a aqueous solution to give a hydroxide ion and cation is said to be strong base.

Explanation

(a)

The order of acid strength by giving the weaker acid first is HNO3>HNO2 , why because an acid strength increases with the number of oxygen atoms that are bonded to the central atoms.

(b)

The order of acid strength by giving the weaker acid first is HCO3<H2CO3 , why because an acid strength decreases with increase in charge of anion for a ployprotic acid species
