Options:

A .

A l^{3 +} = C a^{2 +} = N a^{+}

B .

N a^{+} > C a^{2 +} > A l^{3 +}

C .

N a^{+} > A l^{3 +} > C a^{2 +}

D .

A l^{3 +} > C a^{2 +} > N a^{+}

Answer: Option D
:
D

Greater the valency of the flocculating ion added, greater is its power to cause precipitation (Hardy Schulze rule).
