Identifing Unknown Substances
« on: November 03, 2013, 07:53:13 PM »
If I know that I have four substances unlabeled that are ZnCl2, KNO3, Na2SO3, and NH4Cl and I am given the reagents: H2SO4 , AgNO3, and HCl what could I do to figure out which compounds are which?

I am not convinced you will be able to determine each of the substances (are they given as solids, or as solutions?)

But think what would happen if you dissolve each and add a drop of the silver nitrate.

This is possible using identified Na2SO3
