Question

copper is more reactive than silver,gold and platinum prove with chemical equation

Answer 1

In activity series silver is placed below the copper. hence copper is more reactive than silver.

The more reactive element can displace the less reactive element from its solution.
take two test tubes in  test tube -1 take silver Sulphate solution(white in color) & in test tube-2  take copper Sulphate solution (blue in color). Add copper turnings to test tube -1 and add silver piece to test tube -2 keep the test tubes undisturbed for 15 minutes. After sometime observe the color changes in both test tubes. The color in test tube – 1 changed from white to blue and there is no color change in test tube-2.this indicates in test tube-1 copper displaces silver from its silver Sulphate solution forms copper Sulphate. And in test tube- 2 no displacement reaction takes place. Hence from this experiment we are proving that copper is more reactive than silver.

Answer 2

gold is a most reactive element because it can react with atmospheric air so that's why it is found in undefined shape or gold displace almost all element on periodic table but there is some other elements which is more reactive such as substances which is used in nuclear reaction is more reactive than any one
