Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH scale goes from 0 to 14 with pH 7 as the neutral point. As the amount of hydrogen ions in the soil increases the ...

If the hydrogen ion concentration in a solution increases by a factor of 10, the pH of the solution decreases by 1. A solution of 1 g/dm 3. hydrochloric acid has a pH of 1.6. Predict its pH when ...

The supply of hydrogen ions will also depend upon their concentration, i.e. the pH of the electrolyte. A concentration gradient in the electrolyte is illustrated. ·If the electrolyte is unstirred, the ...

The more concentrated the solution of an acid, the lower its pH will be. If the hydrogen ion concentration in a solution increases by a factor of 10, the pH of the solution decreases by 1 unit.
