5. In a school laboratory, four metals were combined with each of four
solutions and the following reactions occurred: Be(s)+Cd2+ (aq) → Be²+ (aq) + Cd(s) Cd(s) + 2H+ (aq) → Cd²+ (aq) + H (g) Ca²+ (aq) + Be(s)→ No reaction) Cu(s) + H+ (aq) → No reaction Construct a table of relative strengths of oxidizing and reducing agents. (5 marks) Answer: SOA Cu Cd Be Ca SRA 6.
