Zinc chloride can be made from the reaction between zinc oxide and hydrochloric acid. Describe a laboratory method to produce pu
re dry crystals of zinc chloride. (6 marks) Suggest an alternative to zinc oxide that could react with hydrochloric acid to give you the desirable product.(1 mark)
answer: Pure dry crystals of zinc chloride can be produced by crystallisation, then filtration to remove excess solution, followed by drying on a watch glass or in a warm oven.
answer- Yes. The reaction of hydrochloric acid with zinc oxide to form zinc chloride and water is a neutralization reaction because acid (HCl) is a neutralizing base (ZnO).
