Consider the statements S1 and S2
S1 : Conductivity always increases with decrease in the concentration of electrolyte.
S2 : Molar conductivity always increases with decrease in the concentration of electrolyte.
The correct option among the following is :
S1 : Conductivity always increases with decrease in the concentration of electrolyte.
S2 : Molar conductivity always increases with decrease in the concentration of electrolyte.
The correct option among the following is :
Multiple Choice Options
- A Both S1 and S2 are wrong
- B S1 is correct and S2 is wrong
- C Both S1 and S2 are correct
- D S1 is wrong and S2 is correct
Step-by-Step Verified Solution
We know conductivity (k) =
V = volume
When concentration decreases volume increases and when volume increases then conductivity (k) decreases.
So, we can say S1 is incorrect.
We know that,
where
k = conductivity
c = concentration
So, when concentration decreases molar conductivity increases.
So, we can say S2 is correct.
V = volume
When concentration decreases volume increases and when volume increases then conductivity (k) decreases.
So, we can say S1 is incorrect.
We know that,
where
k = conductivity
c = concentration
So, when concentration decreases molar conductivity increases.
So, we can say S2 is correct.
