Which of the following substances react with sodium hydroxide solutions: HCl, CaO, H2SO4, CO2, KCl, CuO?
Which of the following substances react with sodium hydroxide solutions: HCl, CaO, H2SO4, CO2, KCl, CuO? Write down the equations of feasible reactions.
Let’s write down the equations of chemical reactions.
Reaction with hydrochloric acid.
NaOH + HCl = NaCl + H2O.
when sodium hydroxide interacts with hydrochloric acid, sodium chloride and water are formed as a result.
Reaction with sulfuric acid.
2NaOH + H2SO4 = Na2SO4 + 2H2O.
When sodium hydroxide interacts with sulfuric acid, the result is sodium sulfate and water.
Reaction with carbon monoxide.
2NaOH + CO2 = Na2CO3 + H2O.
When sodium hydroxide reacts with carbon monoxide, the result is sodium carbonate and water.
Exchange reaction.
NaOH + KCl = KOH + NaCl.
When sodium hydroxide interacts with potassium chloride, the result is potassium hydroxide and sodium chloride.
