Asample of magnesium oxide was found to be contaminated with magnesium nitrate. to determine the purity of the magnesium oxide, 3.50 g of sample was dissolved in 100.0 ml of 1.50 m hci. 25.0 ml of the resulting solution, which has excess hcl in it, was titrated against 0.200 m naoh solution. the average titration volume was found to be 8.50 ml. (a) write a balanced equation, with state symbols, for the reaction between magnesium oxide and hydrochloric acid. ( 1 mark) (b) calculate the percentage of magnesium oxide in the sample. ( 8 marks ) (c) name the type of titration used in the analysis above.
