Chemistry Challenge -1
10 mL of a solution containing sulphuric acid and hydrochloric acid required 16 mL of N/8 caustic soda solution for neutralisation. On adding excess of barium chloride to 20 mL of the same solution of the mixture of the two acids it gives 0.3501 g barium sulphate. What is the amount of hydrochloric acid per litre in the mixture of acids? (Ba=137.4, O=16, Cl=35.5)
The answer is 1.825.
