Chapter 23, Problem 37E

Interpretation Introduction

Interpretation:

The reason should be determined for expected reasonably the chemistry of dichromate ion which involves mostly in oxidation-reduction reactions and that of chromate ion which involves mostly precipitation reactions.

Concept introduction:

The term oxidation refers to the loss of electrons by a chemical species and the term reduction refers to the gain of electrons by a chemical species. Oxidation -reduction reactions are those chemical reactions in which both oxidation and reduction take place simultaneously. Precipitation reactions are those chemical reactions in which an insoluble salt is formed due to the reaction between two solutions that contain the soluble salts. Thus, an insoluble salt gets formed which is known as a precipitate.
