Alum is double sulphate of trivalent metal like iron- aluminium- chromium etc- and a univalent metal such as potassium or sodium with molecules of water-xA0-e-g- Na2SO4-x22C5-Al2-SO4-3-x22C5-24H2O

Which of the following is an alum?
$K C l \cdot M g C l_{2} \cdot 6 H_{2} O$
$N a A l O_{2}$
$F e S O_{4} \cdot (N H_{4})_{2} S O_{4} \cdot 6 H_{2} O$
$N a_{2} S O_{4} \cdot A l_{2} (S O_{4})_{3} \cdot 24 H_{2} O$

Alum is double sulphate of trivalent metal like iron, aluminium, chromium etc. and a univalent metal such as potassium or sodium with molecules of water.

e.g. $N a_{2} S O_{4} \cdot A l_{2} (S O_{4})_{3} \cdot 24 H_{2} O$
