Tin in silver nitrate, any soln color change?
The solution will remain colourless until silver particles will participated from the solution.

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

$\ce{2 AgNO3(l) -&gt; 2 Ag(s) + O2(g) + 2 NO2(g)}$

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:

$\ce{Sn(NO3)2 + 2AgNO3 + H2O -&gt; Sn(OH)4 + 4HNO3 + 2Ag}$

Analogous silver reactions are described by Tollens' reagent, mirror preparation and gelatin silver process.
