Chapter 4, Problem 18QAP

Interpretation Introduction

(a)

Interpretation:

Hydrogen sulfide should be classified as acid, base, weak acid or weak base.

Concept introduction:

Acids are those compounds which donates a proton to another compound whereas bases are those compounds which accept a proton from another substance.

Acid produces ${\text{H}}^{\text{+}}$ ions when it dissolves in water whereas base produces ${\text{OH}}^{-}$ ions when it dissolves in water.

Strong acid or base is a substance which ionizes completely into its constituents ions in water.

Weak base or acid is a substance which doesn’t ionize completely into its constituents ions in water.

Interpretation Introduction

(b)

Interpretation:

Sulfuric acid should be classified as acid, base, weak acid or weak base.

Concept introduction:

Acids are those compounds which donates a proton to another compound whereas bases are those compounds which accept a proton from another substance.

Acid produces ${\text{H}}^{\text{+}}$ ions when it dissolves in water whereas base produces ${\text{OH}}^{-}$ ions when it dissolves in water.

Strong acid or base is a substance which ionizes completely into its constituents ions in water.

Weak base or acid is a substance which doesn’t ionize completely into its constituents ions in water.

Interpretation Introduction

(c)

Interpretation:

Pyridine, ${\text{C}}_{\text{5}}{\text{H}}_{\text{5}}\text{N}$ should be classified as acid, base, weak acid or weak base.

Concept introduction:

Acids are those compounds which donates a proton to another compound whereas bases are those compounds which accept a proton from another substance.
