Determine the osmotic pressure of a solution prepared by dissolving 25 mg of K2SO4 in 2 litre of water at 25° C, assuming that it is completely dissociated.

Question

Pankaj · Answer

Mass of K 2 SO 4 , w = 25 mg = 0.025g (use 1 g = 1000 mg ) Volume V = 2 liter T = 25 + 273 = 298 K The reaction of dissociation of K2SO4 K 2 SO 4 &rarr; 2K+ + SO 4 2- Number if ions produced = 2+ 1 = 3 So van&rsquo;t Hoff factor i = 3 Now Substituting the values and calculationg we get, &pi;= 5.27 &times; 10 -3 atm

Given, that mass of K 2 ​ S O 4 ​ , w=25 mg=0.025 g Volume V=2 L T=25+273 =298 K The reaction of dissociation of K 2 ​ S O 4 ​ is , K 2 ​ S O 4 ​ → 2 K + + S O 4 2 − ​ Number of ions produced=3=van't Hoff factor Hence, π = i C R T ⟹ π = 3 × 1 7 4 0 . 0 2 5 ​ × 0 . 5 × 0 . 0 8 2 1 × 2 9 8 = 5 . 2 7 × 1 0 − 3 a t m
