1. An oven cleaner solution contained sodium hydroxide. A 25.0 cm³ sample of the oven cleaner solution was placed in a flask. The sample was titrated with hydrochloric acid containing 73 g/dm² of hydrogen chloride, HCL
(a) Describe how this titration is carried out.
(b) Calculate the concentration of the hydrochloric acid in mol/dm³.
Relative atomic masses: H 1; CI 35.5
Answer =. mol/dm³
(c) 10.0 cm³ of hydrochloric acid were required to neutralise the 25.0 cm³ of oven cleaner solution.
(i) Calculate the number of moles of hydrochloric acid reacting.
Answer =. mol
(ii) Calculate the concentration of sodium hydroxide in the oven cleaner solution in mol/dm³.
Answer=. mol/dm3
