4 marksReactivity and Extraction of Metals

CSEC Chemistry · May/June 2017 · Paper 2 · Question 6(a)(i)

In solution, two metals A and B form A⁺ and B²⁺ ions respectively. Metal A displaces Fe from a solution containing Fe²⁺ ions but metal B does NOT.

Arrange the metals A, B and Fe in order of reactivity from LEAST reactive to MOST reactive. Write a balanced chemical equation to show the reaction between metal A and Fe²⁺ ions.

The mark scheme is shown once you've answered.
