MHT CET 2026 Chemistry question
If molar conductance at infinite dilution for and ions are 50 S and 350 S respectively, molar conductivity of M is 20 S . What is the hydrogen ion concentration in of ?
Answer: (C)
Solution
Kohlrausch's law: \Lambda_0(CH_3COOH) = \lambda^0(CH_3COO^-) + \lambda^0(H^+) = 50 + 350 = 400 S . Degree of dissociation . For a weak monobasic acid $ = cα = 5 ×
