1.FeCl_{3}+3KOH\rightarrow Fe(OH)_{3}\downarrow +3KCl
Fe^{3+}+3Cl^{-}+3K^{+}+3OH^{-}\rightarrow Fe(OH)_{3}\downarrow + 3K^{+}+3Cl^{-} 
Fe^{3+}+3OH^{-}\rightarrow Fe(OH)_{3}\downarrow

2.AgNO_{3}+HCl\rightarrow AgCl\downarrow+HNO_{3} 
Ag^{+}+NO_{3}^{-}+H^{+}+Cl^{-}\rightarrow AgCl\downarrow + H^{+}+NO_{3}^{-} 
Ag^{+}+Cl^{-}\rightarrow AgCl\downarrow

3.3ZnSO_{4}+2Na_{3}PO_{4}\rightarrow Zn_{3}(PO_{4})_{2}\downarrow+3Na_{2}SO_{4} 
3Zn^{2+}+3SO_{4}+6Na^{+}+2PO_{4}^{3-}\rightarrow Zn_{3}(PO_{4})_{2}\downarrow+6Na^{+}+3SO_{4}^{2-} 
3Zn^{2+}+2PO_{4}^{3-}\rightarrow Zn_{3}(PO_{4})_{2}\downarrow
