Question

用化学方程式表示下列四种盐各是什么酸和碱反应的产物

BaSO4
CaCl2
CaCO3
NaNO3

Answer 1

BaSO₄:H₂SO₄+Ba（OH)₂==BaSO₄+2H₂O
CaCl₂: Ca（OH）₂+ 2HCl = CaCl₂ + 2H₂O
CaCO₃：CO₂+Ca（OH)₂==CaCO₃+H₂O
NaNO₃：NaOH+HNO₃==NaNO₃+H₂O

望采纳

Answer 2

BaCl2+H2SO4=BaSO4↓+2HCl

Ca（OH）2 + 2HCl = CaCl2 + 2H2O

Ca（OH）2 + H2CO3 = CaCO3↓ +2 H2O

NaOH + HNO3 = NaNO3 + H2O

Answer 3

Ba（OH）2+H2SO4=BaSO4+2H2O
Ca(OH)2+2HCl=CaCl2+2H2O
Ca(OH)2+H2O+CO2=CaCO3沉淀+2H2O,
NaOH+HNO3=NaNO3+H2O

Answer 4

H2SO4+BaOH=BaSO4↓+H2O
Ca(OH)2+2HCl=CaCl2+H2O

CaOH+CO2=CaCO3↓/ CaOH+H2CO3=CaCO3↓+H2O【若有特殊说明CaOH为固态，则无沉淀符号】
NaOH+HNO3=NaNO3+H2O
