With which of the listed substances will sodium hydroxide react: sulfuric acid, potassium oxide, barium, sulfur oxide (Vl), mercury, zinc chloride, phosphorus (V) oxide? Write down the equations of the corresponding reactions ..

1) 2NaOH + H2SO4 → Na2SO4 + 2H2O (sodium sulfate, bases react with acids – neutralization reaction).

2) NaOH + K2O → the reaction does not proceed, since the bases do not react with basic oxides.

3) NaOH + Ba → the reaction does not go, since the bases do not react with metals.

4) 2NaOH + SO3 → Na2SO4 + 2H2O (sodium sulfate, bases react with acid oxides to form salts).

5) NaOH + Hg → the reaction does not proceed, since the bases do not react with metals.

6) 6NaOH + P2O5 → 2Na3PO4 + 3H2O (sodium phosphate, bases react with acid oxides to form salts).
