Question

In an experiment, to determine the percentage purity of the hydrochloric acid, 25cm3 of the acid solution made by dissolving 25.5g of impure acid in a liter of solution was found to neutralize 25cm3 of 0.4M NaOH solution. Calculate a)Concentration of the acid in (i)g/dm3 (ii)mol/dm3 b)percentage purity of the acid c)percentage impurity of the acid

Answer 1

Answer:

State two criteria for determining the purity of a substance ... 25cm3 of this solution neutralized 20cm3 of 0.25M nitric acid. ... Calculate the concentration of the solution in moles per litre.
