Make up the equations of the reactions between potassium hydroxide and the following substances: copper (II) sulfate; sulfur (IV) oxide; phosphorus (V) oxide; sulfur (VI) oxide
1. Potassium hydroxide, reacting with copper sulfate, forms copper (II) hydroxide and potassium sulfate.
2KOH + CuSO4 = Cu (OH) 2 + K2SO4.
2. Sulfur (IV) oxide and potassium hydroxide form potassium sulfite and water.
2KOH + SO2 = K2SO3 + H2O.
3. Phosphorus (V) oxide and potassium hydroxide react with each other to form potassium phosphate and water.
6KOH + P2O5 = 2K3PO4 + 3H2O.
Sulfur oxide (VI) – an acidic oxide, interacting with alkali – potassium hydroxide, form a salt – potassium sulfate and water.
2KOH + SO3 = K2SO4 + H2O.
