Question

Four Metals, A, B, C and D, exhibit the following properties:

a. Only A and C react with 1M HCl to form H2(g)

b. When C is added to solutions of the ions of the other metals, metallic B, D and A are formed

c. Metal D reduces Bn+(aq) ions to form metallic B and Dn+(aq) ions.

Based on this information, arrange the four metals in order of increasing ability to act as reducing agents

Answer: ________________<____________<____________<___________

            Worst Reducing Agent                                                      Best Reducing Agent

Answer: ________________<____________<____________<___________

            Worst Reducing Agent                                                      Best Reducing Agent

Explanation / Answer

answer: B < D < A < C

Explanation :

a) from a statment we know both A and C are reducing agent whicg have greater negative potential and above to H element in the electro chemical series

b) "C"   can replace all ion of A,B,D . so C is the best reducing agent between A and C

c) metal D reduces B+ ion means D is better reducing agent than B. B is worst reducing agent

finally we can create order of reducing nature of all these metal

B < D < A < C
