QUESTION 9 QUESTION 9 In аn experiment, 52 g оf zinc reаcted with 54.75 g оf hydrоchloric аcid to form hydrogen gas and zinc chloride. 9.1 Explain the term limiting reagent. (2) 9.2 Write a balanced chemical equation for the reaction between zinc and hydrochloric acid. (2) 9.3 Perform the necessary calculations to identify the limiting reagent (4) 9.4 Aluminium sulphate is used as a coagulant in water purification. It reacts with sodium hydroxide to form aluminium hydroxide which drags the impurities as it settles. The balanced equation for the reaction is: Al2(SO4)3(aq) + 6NaOH(aq) —> 2Al(OH)3(s) + 3Na2SO4(aq) A chemist at a water purification plant adds 700 g of Al2(SO4)3 to a sample of water 9.4.1 Calculate the maximum mass of Al(OH)3 that can be produced from this mass of Al2(SO4)3. (5) The chemist now dissolves 0,85 mol of Na2SO4 in 250 cm3 of distilled water. He then tops it up with enough distilled water to make a 1 litre solution. 9.4.2. Calculate the concentration of this Na2SO4 solution. (3) [16]
