Write the balanced ionic equations for the following precipitations and complex forming reactions:
a) AgNO3 solution + copper sulphate solution
b) copper sulphate solution + lead nitrate solution
c)CoCl2 solution + conc. HCl
d) Zinc chloride solution + NaOH solution, added slowly until excess
e)Ni(NO3)2 solution + NH3 solution, added slowly until excess
You need to know the solubility rules to predict the products of some reactions. Here is a simplified set of rules.
The second one is
CuSO4(aq) + Pb(NO3)2(aq) ==> PbSO4(s) + Cu(NO3)2(aq)
You turn this into an ionic equation. The others are done the same way. Probably you have learned that Zn(OH)2 is amphoteric and Ni forms the ammine with NH3.
