8.2 The Reactions Of Acids

Question 1

What is produced when an acid and a metal react?

Answer 1

Salt and hydrogen.

Question 2

What is produced when an acid and a carbonate react?

Answer 2

Salt, carbon dioxide and water.

Question 3

What is produced when an acid and a hydrogen carbonate react?

Answer 3

Salt, carbon dioxide and water.

Question 4

What is produced when an acid and a base react?

Answer 4

Salt and water.

Question 5

What is produced when an acid and an alkali react?

Answer 5

Salt and water.

Question 6

When is a salt formed?

Answer 6

When the acidic protons of an acid are replaced by mental ions or the ammonium ions.

Question 7

What are metal oxides generally?

Answer 7

Bases except for a few exceptions that are amphoteric.

Question 8

What are alkalis?

Answer 8

Bases that dissolve in water and the reaction between an acid and an alkali is the same as that between an acid and a base. Alkalis are solutions that contain hydroxide ions.

Question 9

How is ammonia solution (an alkali) reacting with an acid written?

Answer 9

NH3 + HCl —–> NH4Cl (water is omitted)

Question 10

What is a neutralisation reaction?

Answer 10

An exothermic reaction between an acid and an alkali or between an acid and a base to produce salt and water.
