Q 2 Which of the following is most effective in coagulating
negatively charged hydrated ferric oxide sol ?
(i) N a N O 3
(ii) M g S O 4
(iii) A l C l 3
Ans A l C l 3 / A l 3 +

Raveena Sharma · Accepted Answer

The higher the valency of the coagulating ion, greater the
coagulating power of the ion, since the hydrated ferric oxide sol
is negatively charged sol, so the positive ion will coagulate the
sol So, out the given electrolytes Al3+ in
AlCl3 have the highest magnitude of positive charge The
correct option is (iii)
