Question

Tin is more reactive than copper and less raective than iron. Would it react with
A) silver nitrate ?
B) zinc sulfate ?

Answer 1

The solution will remain colourless until silver particles will participated from the solution.

Silver nitrate solution is unstable, its decomposition is accelerated by light:

2AgNO3(l)⟶2Ag(s)+O2(g)+2NO2(g)

That will change the color of the solution to brown. After silver participation, the solution will be colorless again.

A tin strip added to the nitrate solution will dissolve into tin(II) nitrate and will consequently react with silver nitrate accordingly:

Sn(NO3)2+2AgNO3+H2O⟶Sn(OH)4+4HNO3+2Ag
