Electrochemistry · Class 12 · JEE Main Previous Year Question
The variation of molar conductivity with concentration of an electrolyte (X) in aqueous solution is shown in the given figure.
The electrolyte X is:
- a
HCl
- b
NaCl
- c
- d✓
Strategy: Interpret the shape of the vs graph. Linear graphs are for strong electrolytes, while curved "steep" graphs are for weak electrolytes.
Analysis: The provided graph shows a curve that rises steeply at low concentrations and does not approach a finite inter\cept at zero concentration. This "J-shaped" curve is a hallmark of a weak electrolyte.
- , , and are strong electrolytes.
- (A\cetic acid) is a weak electrolyte.
Therefore, the electrolyte X is a\cetic acid.
