Question

Write the balanced chemical equation for the following reactions. Then change each reaction to ionic form; finally to net ionic equations.? a. NaOH(aq) + HCl(aq) = b. Pb(C2H3O2)2(aq) + K2SO4(aq) = c. FeSO4(aq) + (NH4)2S(aq) = d. NaCl(aq) + KOH(aq) =

Answer 1

`a.)` `NaOH(aq) + HCl(aq) rarr NaCl(aq) + H_2O(l)`

Explanation:

And the net ionic equation is simply the protonolysis rxn:

`HO^(-) + H^(+) rarr H_2O(l)`, alternatively,

`HO^(-) + H_3O^(+) rarr 2H_2O(l)`

`b.)Pb(OAc)_2(aq) + K_2SO_4(aq) rarr PbSO_4(s)darr + 2K^(+)""^(-)OAc(aq)`

And the net ionic equation:

`Pb^(2+) + SO_4^(2-) rarr PbSO_4(s)darr`

`c.)FeSO_4(aq) + (NH_4)_2S(aq) rarr FeS(s)darr + (NH_4)_2S(aq)`

And the net ionic equation:

`Fe^(2+) + S^(2-) rarr FeS(s)darr`

`d.)NaCl(aq) + KOH(aq) rightleftharpoons NaOH(aq) + KCl(aq)`

For this last, there is NO macroscopic chemical change.
