Write down the formulas of oxides corresponding to hydroxides, the composition of which is expressed by the formulas: NaOH, KOH, H3PO4, Fe (OH) 2, H2SO3, H2SO4. Divide them into two groups: a) basic; b) acidic. Name the substances.

Sodium hydroxide NaOH – sodium oxide Na2O. Potassium hydroxide KOH – potassium oxide K2O. Phosphoric acid Н3РО4 – phosphorus (V) oxide P2O5. Iron (II) hydroxide Fe (OH) 2 – iron (II) oxide FeO. Sulfurous acid H2SO3 – sulfur oxide (IV) SO2. Sulfuric acid H2SO4 – sulfur oxide (VI) SO3.
A) basic: Na2O, K2O, FeO
B) acidic: P2O5, SO2, SO3.
