SpletQuestion: What is the mass % of aluminum in aluminum sulfate (Al2 (SO4)3) rounded to three significant figures? O 7.90 O 35.7 O 15.8 O 19.4 O 3422 Show transcribed image … SpletNow aluminium is more reactive because it displaces copper. Aluminium + copper(II) sulfate → copper + aluminium sulfate; Scratches on the surface of the oxide layer allow chloride ions to react with aluminium, this effects the cohesiveness of the oxide layer. This allows a simple exchange reaction with the copper(II) sulfate.
