QJEEM20Ch9976: JEE Main 2020 Chemistry - Class 12 JEEM20Ch9976 Solution: Let C NaCl and C BaSO 4 be the conductances (in S) measured for …

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?

Multiple Choice Options

  • A Ionic mobilities of ions from both salts increase with T.
  • B CNaCl(T2) > CNaCl(T1) for T2 > T1
  • C CBaSO4(T2) > CBaSO4(T1) for T2 > T1
  • D CNaCl >> CBaSO4 at a given T

Step-by-Step Verified Solution

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)
