a) Ba(OH)2+2 HCl--->BaCl2+2 H2O
Ba2+ +2 OH- +2 H+ +2 Cl- --->Ba2+ +2 Cl- +2 H2O
2 OH- +2 H+ --->2 H2O
b) 2 LiOH+H2SO4--->Li2SO4+2 H2O
2 Li+ +2 OH- +2 H+ +SO4 2- --->2 Li+ +SO4 2- +2 H2O
c) NaOH+HNO3--->NaNO3+H2O
Na+ +OH- +H+ +NO3- --->Na+ +NO3- +H2O
OH- +H+ --->H2O
d) Mg(OH)2+H2SO3--->MgSO3+2 H2O
Mg2+ +2 OH- +2 H+ +SO3 2- --->Mg2+ +SO3 2- +2 H2O
