Igcse Model Questions Vol1 2025 Chemistry Question 13
Practice objective / multiple choice question 13 from the 2025 Igcse Model Questions Vol1 Chemistry examination.
A 0.500 L aqueous solution of Cu(NO₃)₂ is electrolysed using a constant current of 2.00 A for 30.0 min. At the cathode the reaction is \(\mathrm{Cu^{2+} + 2e^- \rightarrow Cu(s)}\). However, 10 % of the total charge is consumed by the side reaction \(\mathrm{2H_2O + 2e^- \rightarrow H_2 + 2OH^-}\). Calculate the mass of copper deposited on the cathode (in grams).
