(a) Aluminium hydroxide reacts with sulphuric acid to form aluminium sulphate and water. Write a balanced equation for this reaction.(b) Balance the following chemical equation: MnO2 + HCl --------> MnCl2 + Cl2 + H2O
(a) Aluminium hydroxide reacts with sulphuric acid to form aluminium sulphate and water.
$\ 2Al( OH)_{3} \ +\ 3H_{2} SO_{4} \ \rightarrow \ Al_{2}( SO_{4})_{3} \ +\ 6H2O$
(b) The balanced equation is given below:
$MnO_{2} \ +\ 4HCl\ \rightarrow \ MnCl_{2} \ +\ Cl_{2} \ +\ 2H_{2} O$
