Chapter 4.4, Problem 4.12AFP

Interpretation Introduction

Interpretation:

The number of ${\text{OH}}^{-}$ ions that are present in $451\text{ mL}$ of $0.0120M$ calcium hydroxide is to be calculated.

Concept introduction:

A base is a substance that dissociates in water to release ${\text{OH}}^{-}$ ions. Depending upon the strength, bases can be classified into two types:

1. Strong bases

2. Weak bases

Strong bases are the substance that dissociates completely into its ions when dissolved in the solution. They dissociate completely in water to release ${\text{OH}}^{-}$ ions. They behave as strong electrolytes and conduct a large amount of electricity.

Weak bases are the substance that does not dissociates completely into its ions when dissolved in the solution. They dissociate partially in water to release ${\text{OH}}^{-}$ ions. They behave as weak electrolytes and conduct less amount of electricity.
