备战中考化学：无机化学方程式（A打头）
AAg
Ag+2HNO3(浓)=AgNO3+NO2↑+H2O
2AgCl=2Ag + Cl2↑(见光或受热)
AgNO3 + NaCl = AgCl↓ + NaNO3 AgNO3 + NaBr= AgBr↓ + NaNO3
AgNO3 + NaI = AgI↓ + NaNO3
2AgNO3+H2S=Ag2S↓+2HNO3
Ag3PO4+3HNO3=H3PO4+3AgNO3
Al
Al+3O2 2Al2O3(纯氧) 2Al+3S Al2S3 2Al+3Cl2 2AlCl3
4Al(固) + 3O2(气) = 2Al2O3(固) + 3349.3 kJ·mol-1
4Al+3MnO2 2Al2O3+3Mn 2Al+Cr2O3 Al2O3+2Cr
2Al+Fe2O3 Al2O3+2Fe 2Al+3FeO Al2O3+3Fe
2Al + 6HCl = 2AlCl3 + 3H2↑ 2Al+3H2SO4=Al2(SO4)3+3H2↑
2Al+6H2SO4(浓) Al2(SO4)3+3SO2↑+6H2O
Al+4HNO3(稀)=Al(NO3)3+NO↑+2H2O (Al、Fe在冷、浓的H2SO4、HNO3中钝化)
2Al+2NaOH+2H2O=2NaAlO2+3H2↑
Al2O3、Al(OH)3
Al2O3+3H2SO4=Al2(SO4)3+3H2O (Al2O3是两性氧化物)
Al2O3+2NaOH=2NaAlO2+H2O
2Al(OH)3 Al2O3+3H2O
Al(OH)3+3HCl=AlCl3+3H2O 2Al(OH)3+3H2SO4=Al2(SO4)3+6H2O
Al(OH)3+NaOH=NaAlO2+2H2O
铝盐
AlCl3+3NaOH=Al(OH)3↓+3NaCl
AlCl3+3NH3·H2O=Al(OH)3↓+3NH4Cl
2AlCl3+3Na2CO3+3H2O=2Al(OH)3↓+3CO2↑+6NaCl
AlCl3+3NaHCO3=Al(OH)3↓+3CO2↑
AlCl3+3NaAlO2+ 6H2O=4Al(OH)3↓
AlCl3 + 4NaOH = Na + 3NaCl
Al2(SO4)3+3Na2S+ 6H2O=2Al(OH)3↓+3H2S↑
Al4C3 + 12H2O = 4Al(OH)3↓ + 3CH4↑
As
As2O3 + 6Zn + 12HCl = 2AsH3↑ + 6ZnCl2 + 3H2O
3As2S3 + 28HNO3(稀) + 4H2O = 6H3AsO4 + 9H2SO4 + 28NO↑
As2S3 + 28HNO3(浓) = 2H3AsO4 + 3H2SO4 + 28NO2↑ + 8H2O
