Record the reaction in molecular and it is visible between the substances 1) phosphoric acid and potassium hydroxide. 2) copper sulfate and sodium hydroxide. Specify the type of reaction

1) The reaction takes place between substances such as phosphoric acid and potassium hydroxide. As a result of the passage of a chemical reaction, a potassium hydrogen phosphate salt is formed and water is released. This reaction belongs to substitution reactions. Graphically, this equation of a chemical reaction can be expressed as follows:

H3PO4 + 2 KOH = K2HPO4 + 2 H2O

2) Copper sulfate and sodium hydroxide enter into chemical interaction. As a result of the reaction, a substance is formed: sodium sulfate salt and copper hydroxide, which precipitates and has a characteristic bright blue color. This reaction is of the type of exchange.

2 NaOH + CuSO₄ = Na₂SO₄ + Cu (OH) ₂ ↓.
