A 400 ml sample of 1M NaOH is left in a hot plate ovemight, the following morning solution is 1.6M. Then volume of water evaporated is:

100 ml of 1M HCI, 200 ml of 2M HCl and 300 ml of 3M HCl are mixed with enough water to get 1M solution. The volume of water to be added is (in ml)

50 ml of 0.1 M HCl and 50 ml of 0.2 M NaOH are mixed. The pH of the resulting solution is :

50 mL of 0.1 M HCl and 50 mL of 2.0 M NaOH are mixed. The pH of the resulting solution is

3.645g of HCl are dissolved in water to give 1M solution. What is the volume of the solution in ml?

60 ml of 1 M HCl is mixed with 40 ml of 1M NaOH. What is the pHH of resultant solution?

1 ml of 1 M solution is mixed with 999 ml of pure water.

100 ml of 1M NaOH is mixed with 50ml of 1N KOH solution. Normality of mixture is
