1.

- Những oxit phản úng được với nước: $CO_{2}$, $P_{2}$$O_{5}$, $Na_{2}$O, BaO, $SO_{3}$.

$CO_{2}$ + $H_{2}$O → $H_{2}$$CO_{3}$

$P_{2}$$O_{5}$ + 3$H_{2}$O → 2$H_{3}$$PO_{4}$

$Na_{2}$O + $H_{2}$O → 2NaOH

BaO + $H_{2}$O → $Ba(OH)_{2}$

$SO_{3}$ + $H_{2}$O → $H_{2}$$SO_{4}$

- Những oxit phản ứng được với $Ba(OH)_{2}$: $CO_{2}$, $P_{2}$$O_{5}$, $SO_{3}$.

$Ba(OH)_{2}$ + $CO_{2}$ → $BaCO_{3}$ + $H_{2}$O

3$Ba(OH)_{2}$ + $P_{2}$$O_{5}$ → $Ba_{3}$$(PO_{4})_{2}$ + 3$H_{2}$O

$Ba(OH)_{2}$ + $SO_{3}$ → $BaSO_{4}$ + $H_{2}$O

- Những oxit phản ứng được với HCl: MgO, $Fe_{3}$$O_{4}$, CuO, $Na_{2}$O, BaO.

MgO + HCl → $MgCl_{2}$ + $H_{2}$O

$Fe_{3}$$O_{4}$ + 8HCl → 2$FeCl_{3}$ + $FeCl_{2}$ + 4$H_{2}$O

CuO + 2HCl → $CuCl_{2}$ + $H_{2}$O

$Na_{2}$O + 2HCl → 2NaCl + $H_{2}$O

BaO + 2HCl → $BaCl_{2}$ + $H_{2}$O

2.

- Oxit bazơ: FeO (Sắt (II) oxit).

- Oxit axit: $SO_{2}$ (Lưu huỳnh đioxit).

- Axit: $H_{2}$$SO_{3}$ (Axit sunfurơ), HCl (Axit clohiđric).

- Bazơ: $Ba(OH)_{2}$ (Bari hiđroxit), $Cu(OH)_{2}$ (Đồng (II) hiđroxit).

- Muối: $Fe_{2}$$(SO_{4})_{3}$ (Sắt (III) sunfat), Ca(H2PO4)2 (Canxi đihiđrophotphat).
