Textbook Problem

What is the hydronium ion concentration of a 1.2 × 10–4 M solution of HClO4? What is its pH?

Interpretation Introduction

Interpretation:

pH of HClO4 solution should be determined.

Concept introduction:

  • pH of a solution is the negative of the base -10 logarithm of the hydronium ion concentration.

  pH=-log10[H3O+]

  • For an acidic solution pH<7 and for a basic solution pH>7.
Explanation

pH Of a solution is the negative of the base -10 logarithm of the hydronium ion concentration.

  pH=-log10[H3O+]

The given value of hydronium ion concentration of HClO4 is 1.2×104M.  Substituting this value in the above equation,

Then,

  pH=-log10[1
