Waec Model Questions Vol1 2021 Chemistry Question 3
Practice objective / multiple choice question 3 from the 2021 Waec Model Questions Vol1 Chemistry examination.
A 0.500 g piece of an unknown metal Z is reacted with excess dilute H₂SO₄. The reaction produces H₂ gas, and the volume of H₂ collected at STP is 112 mL. The resulting acidic solution is then used to reduce Cu²⁺ ions from a CuSO₄ solution, depositing 0.150 g of copper metal. Assuming the metal forms a sulfate of the type ZSO₄ (i.e., oxidation state +n) and that the reactions proceed with 100 % efficiency, determine the equivalent weight of metal Z.
