Tin in silver nitrate, any soln color change? I have lab question in which a $\ce{AgNO3}$ solution with a tin strip placed in it is mentioned. This isn't a reaction we actually did in the lab, but due to a color change in the solution of one we did do, I was wondering if there would be any for this reaction. Googling I found that the $\ce{AgNO3}$ solution is initially colorless, but that's all I could find. So would there be for this one, or would the solution remain colorless?
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.
