Preparation of soluble salt

In chemistry, what is a salt?

• A product of a reaction between two metals.

• An ionic compound formed by the neutralization of an acid by a base.

• A compound used to preserve meat and clean wounds.

• A substance that always contains sodium chloride.

From what do the two parts of a salt's name typically originate?

• The first part from the acid, the last part from the metal.

• Both parts from the acid.

• The first part from the metal, metal oxide, or metal carbonate; the last part from the acid.

• Both parts from the base.

Why is heating sulfuric acid in a boiling tube placed in hot water safer than heating it directly with a Bunsen burner?

• It prevents the acid from evaporating too quickly.

• It minimizes the risk of knocking over hot acid and rapid reactions causing spills.

• It ensures the acid reaches a higher temperature.

• It allows for better observation of the reaction.

What is the primary reason for adding an excess of copper oxide in the preparation of copper sulfate?

• To ensure the solution becomes more concentrated.

• To speed up the reaction process.

• To ensure all the acid has been neutralized.

• To change the color of the solution.

What is the function of anti-bumping granules when heating a solution?

• They react with the solution to form new compounds.

• They prevent the solution from boiling.

• They help maintain a smooth boiling action and prevent superheating.

• They increase the rate of evaporation.
