1) Fe(CH3COO)3+3HOH=3CH3COOH+Fe(OH)3 pH=7
CH3COO(-) + Fe (3+) +H2O=CH3COOH+Fe(OH)3
2) Cu(CH3COO)2 + 2HOH = 2CH3COOH + Cu(OH)2 pH=7
CH3COO(-) + Cu(2+) + H2O = CH3COOH + Cu(OH)2
3) Al2(SO4)3 + 6HOH = 3H2SO4 + 2Al(OH)3 pH<7 <br> SO4(2-) + Al (3+) + H2O = H2SO4 + Al(OH)3
4) (NH4)3PO4 + 3HOH = H3PO4 + 3NH4OH pH=7
PO4(3-) + NH4(+) + H2O = H3PO4 + NH4OH
5) Ni(NO3)2+ 2HOH = 2HNO3+Ni(OH)2 pH<7<br> NO3(-) + Ni(2+) + H2O = HNO3+Ni(OH)2
