Question

In coagulation of colloids, which ion has high precipitation power

a) Na+

b) K+


c) Ba2+
d) Al3+​

Answer 1

K4[Fe(CN)6] Hint: We know that the Coagulating power depends on the type of colloid. If the Colloid is negative, the ion with highest positive charge will have the highest coagulating power and if the colloid is positive then the ion with highest negative charge will have the highest coagulating power.
