Question

The reaction for tarnish formation due to contact with hydrogen sulphide,
2Ago + H,SO
+H,So → Ag,So, + H2g, and the above tarnish can be removed by using Al metal as
2 Al +3Ag, S → Al,S, +6Ag
The above two reactions appears to be a displacement reactions. But 'Ag’ is less reactive than H
in reactivity series. Then what might be the reason.​

Answer 1

Answer:

Explanation:

+H,So → Ag,So, + H2g, and the above tarnish can be removed by using Al metal as

2 Al +3Ag, S → Al,S, +6
