Question

Equal volumes of M/20 urea solution and M/20 glucose solution are mixed. The mixture will have osmotic pressure:

• A. equal to either of the solution
• B. less than either of the solution
• C. higher than either of the solution
• D. zero

Answer 1

The correct option is A equal to either of the solution

A) Equal to either of the solution

Since equal volumes of urea solution & glucose solution are mixed , therefore the total number of solute particles per unit volume will be same. Since osmotic pressure depends on the number of solute particles therefore osmotic pressure would be same. Also both urea & glucose do not undergo dissociation.
