Question

The decreasing order of electrical conductivity of the following aqueous solutions is : 0.1 M Formic acid (A), 0.1 M Acetic acid (B) 0.1 M Benzoic acid (C)

• A. C > B > A
• B. A > B > C
• C. A > C > B
• D. C > A > B

Answer 1

Answer: (C)

A > C > B

Answer 2

Order of acidic strength
A > C > B
Acidic strength $\uparrow \Rightarrow$ degree of ionization $\uparrow$
