ACIDS, BASES AND SALTS - 2
1. a) Potassium hydroxide and calcium hydroxide are bases which contain hydroxide ions,
OH-. Write the chemical formula of each of these metal hydroxides.
(2)
b) Explain why both of the compounds are also classed as alkalis.
(2)
c) A solution of potassium hydroxide reacts with sulfuric acid in a neutralisation
reaction. Write a balanced equation for the reaction which produces potassium
sulfate as a product.
(2)
d) Calcium hydroxide may neutralise nitric acid. Write a balanced equation for the
reaction which occurs.
