For a neutral solution at 25°C, [H⁺] = [OH⁻] = 1.0 × 10⁻⁷ M
For an acidic solution at 25°C, [H⁺] > 1.0 × 10⁻⁷ M, [OH⁻] < 1.0 × 10⁻⁷ M
In a basic solution at 25°C, [H⁺] < 1.0 × 10⁻⁷ M, [OH⁻] > 1.0 × 10⁻⁷ M

When [OH⁻] = 7.0 × 10⁻¹³ M < 1.0 × 10⁻⁷ M :
The solution is acidic.

When [OH⁻] = 3.8 × 10⁻⁶ M > 1.0 × 10⁻⁷ M :
The solution is basic.

When [H⁺] = 8.3 × 10⁻³ M > 1.0 × 10⁻⁷ M :
The solution is acidic.

When [H⁺] = 9.6 × 10⁻¹⁰ M < 1.0 × 10⁻⁷ M :
The solution is basic.
