JEE Main 2020 — Electrochemistry Question with Solution
From: JEE Main 2020 (Online) 3rd September Morning Slot
Question
Let CNaCl
and CBaSO4 be the conductances (in S) measured for saturated aqueous solutions of NaCl
and BaSO4, respectively, at a temperature T.
Which of the following is false?
Choose an option
Show full solutionCorrect option: D
Correct answer
DCNaCl >> CBaSO4 at a given T
Step-by-step explanation
BaSO4 is sparingly
soluble
salt but NaCl is completely soluble salt so it will produce more number of ions. That is why
Conductance (NaCl) > Conductance (BaSO4)
Conductance (NaCl) > Conductance (BaSO4)
