Solution


Q.

Given below are two statements

Statement-1: The limiting molar conductivities of potassium sulphate is higher compared to that of propionic acid

Statement-2: Molar conductivity decreases with decrease in concentration of electrolyte

In the light of the above statements, choose the most appropriate answer from the options
1 Both statement-1 and Statement-2 are false  
2 Statement-1 is true and Statement-2 is false  
3 Statement-1 is false but Statement-2 is true  
4 Both Statement-1 and Statement-2 are true  

Ans.

(1)

Limiting Λm of weak electrolyte>strong electrolyte

Λm∝volume of solution
