Question

Which solution has the greater concentration?

Answer 1

The higher concentrated solution is 0.250 mole LiCl dissolved in 250 ml of solution

( B).0.250mole of LiCl diluted in 250ml solution

Explanation:

Procedure to find the intensity of the solution:

To find the intensity of the solution, we have to use the following formula

M1V1=M2V2

250mL of a 0.500 M aqueous solution of LiCl is diluted with water

$M1V1=(250) \times (0.500)=125M$

250 ml of a 0.250M aqueous solution of LiCl is diluted with water

$M2V2=(250) \times (0.250)=62.5M$

Thus the PH level of a solution increases from ascending order, Therefore the Solution with 62.5M is a higher concentration than that of the solution with 125M.
