Chapter 5, Problem 24QP

(a)

Interpretation Introduction

Interpretation:

The type of change is to be identified, when ${\text{TiCl}}_4$ reacts with water to give ${\text{TiO}}_2$ and $\text{HCl}$ .

${\text{TiCl}}_4(aq)+2{\text{H}}_2\text{O}(l)\to {\text{TiO}}_2(s)+4\text{HCl}(aq)$

(b)

Interpretation Introduction

Interpretation:

The type of change is to be identified when $\text{Li}(s)$ oxidizes to $2{\text{Li}}_2\text{O}(s)$ .

$4\text{Li}(s)+{\text{O}}_2(g)\to 2{\text{Li}}_2\text{O}(s)$

(c)

Interpretation Introduction

Interpretation:

The type of change is to be identified when $\text{KBr}(s)$ changes to ${\text{K}}^{+}(aq)$ and ${\text{Br}}^{-}(aq)$

$\text{KBr}(s)\to {\text{K}}^{+}(aq)+{\text{Br}}^{-}(aq)$
