Chapter 18.9, Problem 18.11P

(a)

Interpretation Introduction

Interpretation:

The balanced net ionic equation for reaction of ${\text{Rb}}_2{\text{O}}_2$ with water has to be written.

Concept Introduction:

Oxides can be classified into acidic, basic or amphoteric.

• Basic oxides are ionic formed by metal.  Water soluble basic oxide such as ${\text{Li}}_{\text{2}}\text{O}$ and ${\text{Na}}_{\text{2}}\text{O}$ reacts with water to gives ${\text{OH}}^{\text{-}}$ ions.  Basic oxides are placed on the left side of the periodic table.
• Acidic oxides are covalent and they formed by non-metals.  Water soluble acid oxides such as ${\text{P}}_{\text{4}}{\text{O}}_{\text{10}}$ and ${\text{SO}}_{\text{3}}$ dissolved by reacts with water to gives ${\text{H}}^{\text{+}}$ ions.
• Amphoteric oxides act as both acids and bases and dissolves both strong acid and in strong base but insoluble in water.  Acidic oxides are placed on the right side of the periodic table.
