New cards

Define acid

All acids contain H in their formulae. They release H+ ions in aqueous solutions

2
New cards

Define base

Neutralised an acids to form a salt by accepting H+ ions from an acid.

3
New cards

List 4 types of bases

  • Metal oxides

  • Metal hydroxides

  • Metal carbonated

  • Ammonia (only one that is not ionic)


4
New cards

Define alkalis

Bases that dissolve in water by releasing OH- ions in aqueous solutions

Salt + water + carbon dioxide

8

10
New cards

Define a strong acid

A strong acid completely dissociates in aqueous solution

11
New cards

Define a weak acid

A weak acid partially dissociates in aqueous solution
