2Fe + 6HCl---->2FeCl3 + 3H2
CoSO4 + 2NaOH---->Co(OH)2 + Na2SO4
Co(OH)2 + 2HNO3---->Co(NO3)2 + 2H2O
AlCl3 + 3NaOH---->Al(OH)3 + 2NaCl
2Al(OH)3 + 3H2SO4----->Al2(SO4)3 + 6H2O
Al(OH)3 + 3NaOH---->Na3[Al)OH)6]
(NH4)2CO3 + H2SO4---->(NH4)2SO4 + CO2 + H2O
Pb(NO3)2 + 2KI---->PbI2 + 2KNO3
Pb(NO3)2 + 2HCl---->PbCl2 + 2HNO3
