Theoretical/Percent Yield of Tin(II) Iodide
« on: February 10, 2010, 10:40:42 AM »

Does anyone know...
How do you calculate percent yield of SnI2 in a two-part reaction...

Sn(S) + 2HCl-(L) → SnCl2(S) + H2+(G)
0.5463g Sn and 15mL of Hcl were added to get SnCl2. Then...

SnCl2(S) + 2KI-(L) → SnI2(S) +2KCl(S)
to the SnCl2, 2mL of KI were added.

I think that you need to figure out the theoretical yield of SnCl2, but then I don't understand what to do with the second reaction? Do you do another theoretical yield with the KI?

Yes, do the theoretical twice.

Note that you can do it in one step - 1 mole of Sn gives 1 mole of SnI2, no matter what intermediate steps are.
