Acids And Bases

Question 1

What is a base?

Answer 1

A proton acceptor. When in a solution they grab hydrogen ions from water molecules

Question 2

How do acids react with metals and carbonates?

Answer 2

By releasing hydrogen gas. The metal atoms donate electrons to the H+ ions in the acid solution. Metal atoms are oxidised and H+ ions are reduced.

Question 3

What is produced when an acid reacts with a carbonate?

Answer 3

Carbon dioxide + water

Question 4

What happens when acids react with bases and alkalis?

Answer 4

Acids produce H+ ions when dissolved in water and bases produce OH- ions. Acids and bases neutralise each other.

Question 5

What is an acid?

Answer 5

A proton donor. They release hydrogen ions when they are mixed with water

Question 6

Acid + alkali

Answer 6

Salt + water

Question 7

Acid + base

Answer 7

Salt + water

Question 8

What is the state of a salt?

Answer 8

Aqueous solution

Question 9

Acid + carbonate

Answer 9

Salt + water + carbon dioxide

Question 10

Acid + metal

Answer 10

Salt + hydrogen
