Bases - pH Values
pH is a measure of the hydrogen ion (H+) activity in a solution and, therefore, its acidity or alkalinity.
Values for some common bases:
| Base | Normality | pH |
|---|---|---|
| Ammonia | N | 11.5 |
| Ammonia | 0.1 N | 11.1 |
| Ammonia | 0.01 N | 10.6 |
| Barbital sodium | 0.1N | 9.4 |
| Borax | 0.01 N | 9.2 |
| Calcium carbonate | saturated | 9.4 |
| Calcium hydroxide | saturated | 12.4 |
| Ferrous hydroxide | saturated | 9.5 |
| Magnesia | saturated | 10.5 |
| Lime | saturated | 12.4 |
| Potassium acetate | 0.1N | 9.7 |
| Potassium bicarbonate | 0.1N | 8.2 |
| Potassium carbonate | 0.1N | 11.5 |
| Potassium cyanide | 0.1 N | 11.0 |
| Potassium hydroxide | N | 14.0 |
| Potassium hydroxide | 0.1 N | 13.0 |
| Potassium hydroxide | 0.01 N | 12.0 |
| Sodium acetate | 0.1N | 8.9 |
