Question

Write the formula of any new substance or substances produced in considerable amounts when solutions of the following are mixed. Do not list ions already present. If no reaction takes place, write "No Reaction" in the space provided. Assume soluble substances that are being mixed are in solution. In the space below each set of reactants, write the reaction (if any) that occurs between the two substances.

1.Mercuric nitrate + sodium chloride

2. Lead nitrate + excess ammonium hydroxide

3. Silver Chloride + 6M nitric acid

4. Silver chloride + 6M NH4OH

5. Lead nitrate + potassium chromate

6. Mercurous chloride + ammonium hydroxide

Explanation / Answer

1)2NaCl+Hg2(NO3)2---------->2NaNO3+Hg2Cl2

2)Pb(NO3)2+2NH4OH---------->Pb(OH)2 (insoluble in excess NH4OH)+2NH4NO3

3)AgCl+6M HNO3---------->AgNO3+HCl

4)AgCl+6M NH4OH--------->AgOH+NH4Cl

5)Pb(NO3)+K2CrO4-------->PbCrO4+2KNO3

6) Hg2Cl2+2NH4OH--------->Hg+NH4HgCl+NH4Cl+2H2O
