JEE MAIN - Chemistry (2022 - 27th July Evening Shift - No. 4)
Given below are two statements :
Statement I : For KI, molar conductivity increases steeply with dilution
Statement II : For carbonic acid, molar conductivity increases slowly with dilution
In the light of the above statements, choose the correct answer from the options given below :
Both Statement I and Statement II are true
Both Statement I and Statement II are false
Statement I is true but Statement II is false
Statement I is false but Statement II is true
Explanation
Statement I is false : KI is a strong electrolyte
which gets completely dissociate on dissolution.
On dilution, the molar conductivity almost
remain constant.
Statement II is false : carbonic acid is a weak electrolyte which do not gets completely dissociate on dissolution. On dilution the molar conductivity of weak electrolyte increases sharply.

$$ \therefore $$ Both Statements are false.
Statement II is false : carbonic acid is a weak electrolyte which do not gets completely dissociate on dissolution. On dilution the molar conductivity of weak electrolyte increases sharply.
$$ \therefore $$ Both Statements are false.
