Reactions of Acids

Question 1

What is formed during the reactions of metals

Answer 1

Salt and hydrogen are produced. In these reactions, the salt is formed by replacing the hydrogen ions in the acids with metal or ammonium ions.

The general word equation for this is Acid + metal -> salt + hydrogen

Question 2

What is formed during the reactions of metal oxides?

Answer 2

Salt and water are produced when acids react with metal oxides. Metal oxides are bases because they neutralize acids.

The general word equation is acid + metal oxide -> salt + water

Question 3

What is formed during the reactions of metal hydroxides?

Answer 3

Salt and water are produced when acids react with metal hydroxides. Metal hydroxides are bases because they neutralize acids.

In general:

acid + metal hydroxide → salt + water

Question 4

What is formed during the reactions of metal carbonates?

Answer 4

the general word equation is acid + carbonate-> Salt+water+ carbon dioxide

Question 5

Describe the laboratory test for hydrogen

Answer 5

Put a lighted splint near the mouth of the test tube. Hydrogen ignites with a squeaky pop.

Question 6

Describe the laboratory test for carbon dioxide

Answer 6

Bubble the gas through limewater. Carbon dioxide turns limewater milky or cloudy white.
