Chapter 21, Problem 21.147P

Interpretation Introduction

Interpretation:

The given metals has to be arranged in decreasing reducing strength and also has to be divided into 3 groups indicating that those displace ${\text{H}}_{\text{2}}$ from water, from acid and metals that cannot displace ${\text{H}}_{\text{2}}$.

Concept Introduction:

Oxidation: The gain of oxygen or the loss of hydrogen or the loss of an electron in a species during a redox reaction is called as oxidation.

Reduction: The loss of oxygen or the gain of hydrogen or the gain of an electron in a species during a redox reaction is called as reduction.

Strong Acids: Acids that dissociates into ions completely which results in easy donation of protons are considered as strong acids. Strong acid forms weaker conjugated base.

Weak Acids: Acids that do not easily dissociate into ions completely which has difficulty in proton donation are considered as weak acids. Weak acid forms stronger conjugated base

Strong Base: Bases that has strong attraction towards protons and accepts readily. Strong base forms weaker conjugated acid.

Weak Base: Bases that has little affinity towards protons. Weak base forms stronger conjugated acid.
