aluminium hydroxide forms a positively charged sol which of

Aluminium hydroxide forms a positively charged sol. Which of the following ionic substances should be most effective in coagulating the sol?

A. $$NaCl$$

B. $$CaC{l_2}$$

C. $$F{e_2}{\left( {S{O_4}} \right)_3}$$

D. $${K_3}P{O_4}$$

Answer : $${K_3}P{O_4}$$

Solution :
$$Al{\left( {OH} \right)_3}$$ is positively charged sol. $${K_3}P{O_4}$$ has greater negative charge. Hence, it is most effective in coagulation
