# Calculating \([H_3O^+]\) and \([OH^-]\) in Solutions

## Overview

The ion product constant of water reveals that a solution's concentrations of hydronium ion \([H_3O^+]\) and hydroxide ion \([OH^-]\) are inversely proportional since they are on the same side of the equation. If a solution's concentration of \([H_3O^+]\) increases, then its concentration of \([OH^-]\) decreases. Similarly, if a solution's concentration of \([H_3O^+]\) decreases, then its concentration of \([OH^-]\) increases. This section also reveals that if the concentration of either the hydronium ion or the hydroxide ion is known, then the concentration of the other can be calculated using the ion product constant of water.

## Part A

Determine whether the following hydroxide ion concentrations \([OH^-]\) correspond to acidic, basic, or neutral solutions by estimating their corresponding hydronium ion concentrations \([H_3O^+]\) using the ion product constant of water \((K_w)\).

### Table: Relationship between Hydronium Ion Concentration and Solution Condition

| Hydronium ion concentration \([H_3O^+]\) | Solution condition |
|------------------------------------------|--------------------|
| Greater than \(1 \times 10^{-7} M\)      | Acidic             |
| Equal to \(1 \times 10^{-7} M\)          | Neutral            |
| Less than \(1 \times 10^{-7} M\)         | Basic              |

### Task

Place the hydroxide ion concentrations into the correct categories based on the solution condition:

- \([OH^-] = 4 \times 10^{-12} M\)
- \([OH^-] = 3 \times 10^{-9} M\)
- \([OH^-] = 8 \times 10^{-10} M\)
- \([OH^-] = 4 \times 10^{-13} M\)
- \([OH^-] = 2 \times 10^{-2} M\)
- \([OH^-] = 7 \times 10^{-4} M\)
- \([OH^-] = 5 \times 10^{-5} M\)
- \([OH^-]
