Question

How does the electrical conductivity of 20 ml of 0.2 M – MgSO4 change when 0.5 M – Ba(OH)2 solution is gradually added in it, to excess?

Options

A.decreases continuously
B.increases continuously
C.increases and then decreases
D.decreases and then increases

Solution

MgSO4(aq) + Ba(OH)2 (added) ? Mg(OH)2(s) + BaSO4(s)

First number of ions decreases and then increases.
