Chapter 4, Problem 10SAQ
Interpretation Introduction

Interpretation:

The net ionic equation for the reaction when aqueous solutions of KOH and SrCl2 are mixed is to be identified.

Concept Introduction: Ionic equation is the balanced molecular equation in which the strong electrolytes are broken down to form their ions that are dissolved in an aqueous solution.

To identify: The net ionic equation for the reaction when aqueous solutions of KOH and SrCl2 are mixed.

Correct answer: The correct option is (b).

Reason for correct answer:

The molecular equation when aqueous solution of KOH and SrCl2 are mixed is,

    2KOH(aq)+SrCl2(aq)2KCl(aq)+Sr(OH)2(s)

For the ionic equation, the molecular equation is written in the form of cations and anions of aqueous species separately,

    2K+(aq)+2OH(aq)+Sr2+(aq)+2Cl(aq)2K+(aq)+2Cl(aq)+Sr(OH)2

To get the ionic equation, the common ions are cancelled. The net ionic equation obtained for the given reaction is,

    2OH(aq)+Sr2+(aq)Sr(OH)2(s)

Reason for incorrect options:

The other three options (a), (c) and (d) are incorrect because they do not produce the cations and anions that match the net ionic equation.
