Answer to Question #16808 in Inorganic Chemistry for Amiin
An excess of calcium hydroxide is added to an acidic soil. What happens to the pH of the soil?
Calcium Hydroxide (or Slaked Lime) is a strong base (as are all metal hydroxides, oxides, and carbonates).A Calcium Hydroxide is a substance with a pH of 8 or more. When an acid and a base react, the result is that a salt and water is formed. This also has the effect of neutralising a substance. So slaked lime is added in order to reduce the acidity of the soil.
