Chapter 10, Problem 10.1EP

In Arrhenius acid–base theory, what ion is responsible for the properties of

1. a. acidic solutions
2. b. basic solutions

Interpretation Introduction

Interpretation:

According to Arrhenius acid–base theory, the ion that is responsible for the properties of acidic solutions has to be given.

Concept Introduction:

Arrhenius acid-base theory:

Arrhenius acid is a substance that gives out hydrogen ions in water.

Arrhenius base is a substance that gives out hydroxide ions in water.

Explanation of Solution

Arrhenius acid is a molecular compound that produces hydrogen ions when dissolved in water.  The ion that is responsible for the acidic property of solution is hydrogen ion, ${\text{H}}^{+}$ ion.

Interpretation Introduction

Interpretation:

According to Arrhenius acid–base theory, the ion that is responsible for the properties of basic solutions has to be given.

Concept Introduction:

Arrhenius acid-base theory:

Arrhenius acid is a substance that gives out hydrogen ions in water.

Arrhenius base is a substance that gives out hydroxide ions in water.

Explanation of Solution

Arrhenius base is an ionic compound that produces hydroxide ions when dissolved in water.  The ion that is responsible for the basic property of solution is hydroxide ion, ${\text{OH}}^{-}$ ion.
