Question
Find the freezing point of a solution when 5 mol of KI is mixed with 1 mol of HgCl2 in 3500 gram of H2O. Kf of H2O = 1.86 K/m. (KI + HgCl2 → K2HgI4 + KCl)

Answer: D
💡 Solution & Explanation
2 2 4 4KI HgCl K HgI 2KCl Remained KI = 5 – 4 = 1 mol 1 mol K2HgI4 and 2 mol KCl is formed. 2 2 4 4 (K HgI 2K HgI ) f o f 1 1 2 2 3 3 ( T ) K (i m i m i m ) o f 0 (T )
