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 ... Kits (pH) containing the necessary chemicals and color ...

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 pH of a solution is a measure of its concentration of hydrogen ions. The higher the concentration of H + ions in an acidic solution, the lower the pH. A pH of 1 represents a hydrogen ion ...

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 ...
