Chapter 21, Problem 23QAP

Interpretation Introduction

(a)

Interpretation:

The balanced equation for the reaction of ammonia with ${\text{Cu}}^{\text{+2}}$ should be determined.

Concept introduction:

Ammonia is a Lewis base because of lone pair of electrons on nitrogen atom. So, it canform coordinate bond with electron deficient molecules. The reaction of ammonia with copper ions results a deep blue color complex.

Interpretation Introduction

(b)

Interpretation:

The balanced equation for the reaction of ammonia with ${\text{H}}^{+}$ should be determined.

Concept introduction:

Ammonia is a weak base as it has lone pair on Nitrogen atom. So, it can accept a proton and forms ammonium ion.

Interpretation Introduction

(c)

Interpretation:

The balanced equation for the reaction of ammonia with ${\text{Al}}^{\text{+3}}$ should be determined.

Concept introduction:

Reaction of aluminum ion with ammonia results aluminum hydroxide which is a white precipitate and ammonium ion.
