Reactions of acids and bases

Question 1

General equation for reactions

Answer 1

Metal + acid -> ionic salt + hydrogen gas

Question 2

Metal carbonate reaction equation

Answer 2

Acid + metal carbonate –> ionic salt + CO2 + H2O

Question 3

What is a metal carbonate reaction?

Answer 3

Contains metal cations and carbonate ions, where bases react with acids. When added to water, soluble will dissociate into cations and carbonate ions. Insoluble carbonates will remain solid when added to water

Question 4

Metal hydrogencarbonate (bicarbonate) reaction

Answer 4

Acid + metal hydrogencarbonate –> ionic salt + CO2 + H2O

Question 5

Metal hydroxide reaction equation

Answer 5

Acid + Metal hydroxide -> ionic salt + H2O

Question 6

Neutralisation reaction equation

Answer 6

Acid and base remove each other from solution and form water
Acid + Metal hydroxide -> ionic salt + H2O

Question 7

What are antacids?

Answer 7

Weak bases that neutralise the effect of excess stomach acid (HCl)
