Chapter 14, Problem 14.127CQ

Interpretation Introduction

Interpretation:

The molarity of H₂SO₄ for the given solution should be determined.

Concept introduction:

• Neutralization is the reaction between acid and base
• The ratio depends mostly on the hydroxide and hydronium present in each species
• The endpoint is present when hydronium ions equal hydroxide ions.

To determine: The molarity of H₂SO₄ for the given solution.

Given:

Molarity of NaOH = 0.205 M

Volume of H₂SO₄ = 20.0 mL

Volume of NaOH = 45.6 mL

The reaction between NaOH and H₂SO₄ is:

  ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}\text{(aq)+2NaOH(aq)}\to {\text{2H}}_{\text{2}}{\text{O(l)+Na}}_{\text{2}}{\text{SO}}_{\text{4}}\text{(aq)}$
