Đáp án + giải thích các bước giải:
- Oxit axit `+` Bazo ` \to` Muối `+H_2O`
`SO_2+2KOH \to K_2SO_3+H_2O`
`SO_2+2NaOH \to Na_2SO_3+H_2O`
`SO_3+Ca(OH)_2 \to CaSO_4↓+H_2O`
`CO_2+Ba(OH)_2 \to BaCO_3↓+H_2O`
`P_2O_5+6NaOH \to 2Na_3PO_4+3H_2O`
- Bazo `+` Axit `\to` Muối `+H_2O`
`NaOH+HCl to NaCl+H_2O`
`Ca(OH)_2+H_2SO_4 \to CaSO_4↓+2H_2O`
`Ba(OH)_2+H_2SO_4 \to BaSO_4↓+2H_2O`
`KOH+HNO_3 \to KNO_3+H_2O`
`Fe(OH)_2+2HCl \to FeCl_2+2H_2O`
- Bazo không tan bị nhiệt phân hủy
$2Fe(OH)_3\xrightarrow[]{t^o}Fe_2O_3+3H_2O$
$Cu(OH)_2\xrightarrow[]{t^o}CuO+H_2O$
$2Al(OH)_3\xrightarrow[]{t^o}Al_2O_3+3H_2O$
$Mg(OH)_2\xrightarrow[]{t^o}MgO+H_2O$
$Zn(OH)_2\xrightarrow[]{t^o}ZnO+H_2O$
