酸加碱生成碱盐和另一种物质的化学式

碱＋酸→盐＋H2O
Cu(OH)2+2HCl==CuCl2+2H2O Cu(OH)2+H2SO4==CuSO4+2H2O
NaOH+HCl==NaCl+H2O 2NaOH+H2SO4==Na2SO4+2H2O
NaOH+HNO3==NaNO3+H2O Mg(OH)2+2HNO3==Mg(NO3)2+2H2O
Ba(OH)2+H2SO4==BaSO4↓+2H2O
盐＋碱→新盐＋新碱
CuSO4+2NaOH==Cu(OH)2↓+Na2SO4 FeCl3+3NaOH==Fe(OH)3↓+3NaCl
Ca(OH)2+Na2CO3==CaCO3↓+2NaOH NaOH+NH4Cl==NaCl+NH3↑+H2O
