equal volume each of two sols of agi one obtained by adding

Equal volume each of two sols of $$AgI,$$ one obtained by adding $$AgN{O_3}$$ to slight excess of $$KI$$ and another obtained by adding $$KI$$ to slight excess of $$AgN{O_3},$$ are mixed together. Then :

A. the two sols will stabilize each other

B. the sol particles will acquire more electric charge

C. the sols will coagulate each other mutually

D. a true solution will be obtained

Answer : the sols will coagulate each other mutually

Solution :
The sols obtained in the two cases will be oppositely charged to coagulate each other.
