MHT CET 2025 Chemistry question
What is molar conductivity at zero concentration in for aluminium sulphate, if molar ionic conductivities at zero concentration of and are 189 and 50.1 respectively?
Answer: (D)
Solution
By Kohlrausch's law, . Aluminium sulphate is Al_2(SO_4)_3 \rightarrow 2Al^{3+} + 3SO_4^{2-}, so m^0$ = 2(189) + 3(50.1) = 378 + 150.3 = 528.3\
