Chapter 9, Problem 78E

Interpretation Introduction

Interpretation:

Whether the reaction that occurs when aqueous solutions of hydrofluoric acid and potassium hydroxide are combined is an example of redox reaction or precipitation reaction is to be predicted based on the activity series and solubility guidelines. The net ionic equation is 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.
