Question

Use the solubility table to answer the following. You do not need to mix any chemicals. Circle all of the following compounds that will dissolve completely (or form a ppt) in HCl(aq) Al(OH)_3(s) CuCO_3(s) Pb(NO_3)_2(aq) CaSO_4(s) BaCl_2(aq) AgNO_3(aq) Circle all of the following solutions that will precipitate with addition of CuSO_4 NaOH(aq) BaCl_2(aq) Pb(NO_3)_2(aq) K_2CO_3(aq) CuCl_2(aq) NH_4Cl(aq) Circle all of the following compounds that will precipitate with addition of Mg(IO_3)_2(aq) CaCl_2(aq) NH_4OH(aq) ZnSO_3(aq) Ba(NO_3)_2(aq) Pb(NO_3)_2(aq) K_2CO_3(aq) Write the precipitate(s) that will form and remain when the following solutions are mixed: excess H_2SO_4(aq) + Ba (NO_3)_2(aq) + K_2CO_3 excess NaOH (aq) + CuCl_2(aq) Pb(NO_3)_2(aq) A student divides an unknown compound into two tests tubes and performs these tests: When excess Pb(NO_3)_2 is added to the first tube there is a precipitate When excess H_2SO_4 is added to the second test tub

Explanation / Answer

1. CuCO3, AgNO3 (aq)

2. BaCl2, Pb(NO3)2,

3. CaCl2, ZnSO4,Ba(NO3)2, Pb(No3)2.

4.Ba2SO4

PbCl2

5.

AgNo3 + Pb(No3)2 = Ag(No3)2 + PbNo3

AgNO3 + H2SO4 = Ag2SO4 + HNO3

The unknown compound is AgNO3
