A volume of 24 ml of 0.25 M solution is diluted to 200 ml. In this solution, 50 ml of 2 M is added. 25 ml of this mixture is titrated with 20 ml of solution. The molarity of the solution is
Options:
Answer:
B
Solution:
mmol = 24 0.25 = 6; after dilution and acid addition (total 250 ml) it is 0.024 M. 25 ml holds 0.6 mmol = 3 meq. has = 3, so molarity = 3/(20 3) = 0.05 M, option (b).
