Question

How would you test for the presence of the following ions in aqueous
solution of an unknown salt?
Give a Brief description of test and the Observations if test is
positive

I-
Reaction equation to account for observation:

CO32-
Reaction equation to account for observation:

Ag+
Reaction equation to account for observation:

Ba2+
Reaction equation to account for observation:

Answer 1

I- + Pb 2+ = PbI2

Mn2+ + CO32- = MnCO3

Ag+ + Cl- = AgCl.

Ba2+ + SO42-= BaSO4
