JEE Mains · Chemistry · STD 12 - 2. Electrochemistry
Consider the statements \(S_1\) and \(S_2\):
\(S_1\): Conductivity always increases with decrease in the concentration of electrolyte.
\(S_2\): Molar conductivity always increases with decrease in the concentration of electrolyte.
The correct option among the following is
- A \(S_1\) is wrong and \(S_2\) is correct
- B Both \(S_1\) and \(S_2\) are wrong
- C \(S_1\) is correct and \(S_2\) is wrong
- D Both \(S_1\) and \(S_2\) are correct
Answer & Solution
Correct Answer
(A) \(S_1\) is wrong and \(S_2\) is correct
Step-by-step Solution
Detailed explanation
We know that \(\lambda _m=\frac {K}{C}\) Here \(\lambda _m\,=\) molar conductivity \(K=\) conductivity \(C\,=\) concentration when concentration increase conductivity always increases. The molar conductivity always increase wih the decrease in the concentration
