Chapter 18, Problem 18.61SP

Interpretation Introduction

Interpretation:

If an element forms an ionic hydride, it is more likely forms either acidic oxide or basic oxide has to be explained.

Concept Introduction:

Oxides can be classified into acidic, basic and amphoteric.

• Basic oxides are ionic they are 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.  Acidic oxides are placed on the right side of the periodic table.
• Amphoteric oxides act as both acids and bases and dissolves both strong acid and in strong base but insoluble in water.
