Explanation / Answer

a) H3PO4(aq) + 3 NaOH(aq) ---> Na3PO4(aq) + 3 H2O
now we must determine what becomes ion and what doesn't
H3PO4(aq) ionizes ( OK, not completely, but let's just pretend it does )
NaOH(aq) is a soluble ionic compound
Na3PO4(aq) is a soluble ionic compound
H2O is a molecule

b) 3H+ + PO4-3 + 3Na+ + 3OH- ---> 3Na+ + PO4-3 + 3 H2O
sodium and phosphate ions remain unchanged - they are spectators
so

c) H+ + OH- ---> H2O (all the 3's reduce to 1)
