Chapter 9, Problem 64E

Interpretation Introduction

Interpretation:

Whether the reaction that occurs when aqueous solutions of sodium cyanide and hydrobromic acid are mixed is an example of redox reaction or precipitation reaction has to be predicted based on the acitivity series and solubility guidelines. The net ionic equation has to be written.

Concept introduction:

Metals are tabulated in decreasing order of their reducing power or increasing order of their oxidizing power. The table is termed as activity series. Any element in the activity series will replace the ions of the elements from a solution, written below it. If the product formed is an insoluble compound, the reaction is termed as precipitation reaction. If the elements in the reactants undergo oxidation and reduction, the reaction is termed as redox reaction.
