Chapter 10.11, Problem 3QQ

Interpretation Introduction

Interpretation:

The correct chemical equation for the aqueous solution hydrolysis of the ${\text{CN}}^{\text{-}}$ ion has to be identified.

Concept Introduction:

Basic hydrolysis: The reaction of the negative ion from a salt with water to produce the ion’s conjugate acid and hydroxide ion.

$\begin{array}{l}{\text{CN}}^{\text{-}}\text{+}{\text{H}}_{\text{2}}\text{O }\underset{}{\overset{}{\to }}\text{HCN +}{\text{OH}}^{\text{-}}\text{(Basic}\text{solution)}\\ \\ \text{Proton}\text{Proton}\text{Weak}\text{acid}\\ \text{acceptor}\text{donar}\end{array}$
