The following substances are given: CaO, Cu (OH) 2, HKl, KBr, SO2, H2S, N2O5. Which ones react with sodium hydroxide?
Sodium hydroxide is an alkali. Alkalis react with acids, acid oxides, and salts (if gas, water or precipitate is formed).
2NaOH + SO2 = Na2SO3 + H2O.
2NaOH + H2S = Na2S + H2O.
2NaOH + N2O5 = 2 NaNO3 + H2O.
NaOH + HCl = NaCl + H2O.
