(Answered) When metal x is placed in a solution of y2 the surface of

Academics

When metal X is placed in a solution of Y2+, the surface of metal X changes colour. When metal Y is placed in acid solution, colourless gas bubbles form on the surface of the metal. When metal X is placed in a solution of Z2+, no change is observed in the solution or on the surface of metal X.

Will metal Z cause formation of H2 when placed in acid solution? Explain your answer.
