Each question contains STATEMENT-I(Assertion) and STATEMENT-2(Reason).the statement carefully and mark the correct answer accoring to the instrution given below:
STATEMENT - 1 : Isotonic solutions must have the same molal concentration.
STATEMENT - 2 : Solution which have the same osmotic pressure are known as isotonic solution.

A

Statement-1 is true , statement-2 is true , statement-2 is a correct explanation for statement-1

B

Statement-1 is true , statement-2 is true , statement-2 is not a correct explanation for statement-1

C

Statement-1 is true , statement-2 is false

D

Statement-1 is false , statement-2 is true

Text Solution

Verified by Experts

The correct Answer is:
D
It is not necessary that solutions at same molar concentration have same osmotic pressure e.g.,
`pi(0.1MNaCl)gtpi(0.1M" glucose")` because NaCl is ionised.
