Chapter 16, Problem 16.108QP

(a)

Interpretation Introduction

Interpretation:

The balanced ionic equations for the reaction of ${\text{Zn(OH)}}_{\text{2}}$ with $\text{HCl}\text{and}\text{NaOH}$ has to be written.

Concept Information:

Oxides of metals and non-metals may be,

Acidic-exhibits acidic character

Basic-exhibits basic character

Amphoteric-exhibits both acidic and basic  character

Neutral-does not exhibit any of the acidic or basic character

Metal hydroxides:

Except ${\text{Be(OH)}}_{\text{2}}$, all the alkali and alkaline earth metals are basic.

Hydroxides like  ${\text{Be(OH)}}_{\text{2}},{\text{Sn(OH)}}_{\text{2}},{\text{Pb(OH)}}_{\text{2}}\text{etc}$ are amphoteric.

To write: The balanced ionic equations for the reaction of ${\text{Zn(OH)}}_{\text{2}}$ with $\text{HCl}$
