Chapter 21, Problem 10QAP
Interpretation Introduction

(a)

Interpretation:

To write the formula of sodium azide.

Concept introduction:

Azide ion (N3) is the conjugate base of hydrazoic acid (NH3).

Interpretation Introduction

(b)

Interpretation:

To write the formula of sulfurous acid.

Concept introduction:

The name of an acid depends on the anion. For acid having three elements,

  1. ‘-ate’ is the general suffix for oxyanions. In naming acid, the ‘ate’ changes to ‘ic acid’. For example, sulphate ion (SO42), nitrate ion (NO3), etc.
  2. '-ite' is the suffix for oxyanions (same charge, number of O-atoms reduced to one).For example, sulfite ion (SO32), nitrite ion (NO2), etc. In naming acid containing oxyanions, ‘ite’ changes to ‘ous’.
  3. ‘per’ is the prefix for oxyanions (with Oatoms1) that ends with suffix ‘-ate’.
  4. ‘hypo’ is the prefix for oxyanions (with less O-atoms) than the oxyanion that ends with suffix ‘-ate’.

Interpretation Introduction

(c)

Interpretation:

To write the formula of hydrazine.

Concept introduction:

The compound hydrazine consists of nitrogen and hydrogen atoms.

Interpretation Introduction

(d)

Interpretation:

To write the formula of sodium dihydrogen phosphate.

Concept introduction:

The atoms present in the compound dihydrogen phosphate are- sodium, hydrogen, phosphorus and oxygen.
