    Arrange metal activity series based on reations

    1. Four metals are tested: A,B,C,D. If A is more active than C and C is more active than B, is it necessary to test A and B? Explain your answer.

    2. You observe that when copper is added to a solution containing gold ions, the copper dissolves and the gold precipitates. Similarly, almost all other metals will displace gold from solutions of good salts.

    a) Do these observations mean that the gold ion is a good oxidizing agent or a poor oxidizing agent? Explain

    b) Expensive electronic equipment use gold-coated parts. Explain why this is based on chemical behavior.

    Metal Activity Series

    1. Four metals are tested: A,B,C,D. If A is more active than C and C is more active than B, is it necessary to test A and B? Explain your answer.

    Solution:

    It is not necessary to test A and B. Because we know that
    A > C, C > B. It must be true that A > B That is, A is more active than B.

    Or we can ...

    Solution Summary

    In this solution, students are given the reactions of A with C, B with C. Students are asked to arrange the metal ions from the best oxidizing agent to the worst oxidizing agent.
