Gce Model Questions Vol1 2017 Chemistry Question 47
Practice objective / multiple choice question 47 from the 2017 Gce Model Questions Vol1 Chemistry examination.
A 0.250 g sample of impure copper metal is dissolved in excess nitric acid, producing Cu²⁺ ions. The solution is then titrated with 0.100 M Fe²⁺ solution until the reaction \( \text{Cu}^{2+}+\text{Fe}^{2+}\rightarrow\text{Cu}^{+}+\text{Fe}^{3+} \) is complete. It required 18.5 mL of the Fe²⁺ solution. Assuming all copper in the sample reacts, calculate the percentage purity of the copper metal.
