Question

1. Make the conversion (check photo)

2. Propose and write down 3 reactions for obtaining Cuprum (II) Sulfate
3. Describe the chemical properties of amphoteric compounds? What classes of compounds do they interact with?

Answer 1

Three reactions for obtaining Cuprum (II) Sulfate are:a) Reaction between Copper (II) Oxide and Sulfuric Acid:

CuO + H2SO4 → CuSO4 + H2Ob) Reaction between Copper (II) Hydroxide and Sulfuric Acid:

Cu(OH)2 + H2SO4 → CuSO4 + 2H2Oc) Reaction between Copper (II) Carbonate and Sulfuric Acid:

CuCO3 + H2SO4 → CuSO4 + H2O + CO2Amphoteric compounds are those that can act as both an acid and a base. These compounds can donate a proton in acidic conditions or accept a proton in basic conditions. The chemical properties of amphoteric compounds depend on the pH of the solution they are in. In an acidic solution, amphoteric compounds act as bases and accept protons, while in a basic solution, they act as acids and donate protons.Amphoteric compounds can interact with both acidic and basic compounds. They can react with acids to form salts and with bases to form hydroxides. Examples of amphoteric compounds include water, amino acids, and metal oxides such as aluminum oxide and zinc oxide. These compounds are important in many chemical processes, including acid-base reactions, redox reactions, and precipitation reactions.:
