five test tubes

Post  kakakwan on Mon Apr 22, 2013 10:54 am

I have five test tubes randomly labelled as A, B, C, D and E.
Each of the test tubes contains one of the following colorless solution:
HNO3(aq), CaCl2(aq), NaCl(aq), NaCO3(aq), Pb(NO3)2(aq)
mix the solution and from the observations, distinguish what A, B, C, D and E are.
And the chemical equation are needed??
How do i know
Please help me!!
