The following substances are given: CaO, Cu (OH2), HCl, KBr, SO2, H2S, N2O5. Which ones react with sodium hydroxide? Write down the equations of the reactions taking place.

According to the condition, we were given the substance sodium hydroxide, the chemical formula is NaOH. Sodium hydroxide is a strong base with pronounced alkaline properties, therefore it will interact with substances that have acidic properties.

Sodium hydroxide reacts with hydrochloric acid to form sodium chloride and water salt.

HCl + NaOH = NaCl + H2O

Sodium hydroxide interacts with tetravalent sulfur oxide. The sodium sulfide salt and water are formed.

2 NaOH + SO2 = Na2SO3 + H2O

Sodium hydroxide reacts with the sulfur sulfate salt to form the sodium sulfate salt and water.

H2S + 2 NaOH = Na2S + 2 H2O

Sodium hydroxide interacts with pentavalent nitric oxide. Formed salt nitrate nitrogen and water.

N2O5 + 2 NaOH = 2NaNO3 + H2O.
