प्रश्न
The molar conductivity of CH3COOH at infinite dilution is 390 Scm2/mol. Using the graph and given information, the molar conductivity of CH3COOK will be:
पर्याय
100 Scm2/mol
115 Scm2/mol
150 Scm2/mol
125 Scm2/mol

उत्तर
115 Scm2/mol
Explanation:
Λ°CH3COOK = Λ°CH3COOH + Λ°KCl – Λ°HCl
= 390 + 150 – 425
= 115 Scm2/mol
