1)2KOH+H2SO4=K2SO4+2H2O

+ - + 2- + 2-

2K+2OH+2H+SO4=2K+SO4+2H2O

+ -

2H+2OH=2H2O

+ 2- 2+ - + -

2) K2SO4+Ba(Cl)2=2KCl+BaSO4(осадок)

+ 2- 2+ - + -

2K+SO4+Ba+2Cl=2K+2Cl+BaSO4

2+ 2-

Ba+SO4=BaSO4

+ - + - + -

3)KCl+AgNO3=KNO3+AgCl

+ - + - + -

K+Cl+Ag+NO3=K +NO3+AgCl

+ -

Ag+Cl=AgCl

Ba → Ba(OH), → BaCO3 → CO2 → C6H12O6 →C2H5OH→ CH3CHO -> CH3COOH
