Chapter 15, Problem 45QAP

Interpretation Introduction

Interpretation:

An overall net ionic equation needs to be determined. The value of K for the reaction where ${\text{CoCO}}_{\text{3}}$ is dissolved by ${\text{Na}}_{\text{2}}{\text{C}}_{\text{2}}{\text{O}}_{\text{4}}\left({\text{Na}}_{\text{2}}\text{ox}\right)$ Na₂ to form ${\left[{\text{Coox}}_3\right]}^{4-}\left(K_f=5\times {10}^9\right)$ needs to be determined.

Concept introduction:

Net ionic equation is the ionic equation in which reactants are written in the form of ions if they occur as ions in a reaction medium and product form are shown as combination of ions. The charges of ions and each atom in the reaction are balanced.

K can be calculated as follows:

$K=K_f\times K_{sp}$

Where, $K_f$ is the formation constant and $K_{sp}$ is solubility product constant.
