Question

100ml of 0.1M Hcl + 100 ml of 0.2M H2so4 +100 ml of 0.1M HNO3 are mixed together.
(a) What is the final concentration of the solution.
(b) what should be the final concentration of the solution if the solution is made to 1L by adding H2O?

Answer 1

THINGS TO REMEMBER:

• On dilution of solution with water the number of moles of solute does not change
• M= n/ V where n is no of moles and V is volume of solution
• n when there is a mixture will be the total number of moles and V will he the total volume .
