Question

How would you know that silver is chemically less reactive than copper?

Answer 1

When silver react with Cupper sulphate no reaction found,

Ag(s) + CuSO4(aq)------> no reaction,

While Cu replace Ag From AgNO3,

So we can say that Ag is less reactive than Cu.

Cu(s) + 2AgNO3(aq)------> Cu(NO3)2(aq) + 2Ag(s)
