Acids and Bases Neutralises Each Other
An ACID is a substance with a pH of less than 7. Acids form H+(aq) ions in water.
A BASE is a substance with a pH of greater than 7.
An ALKALI is a base that dissolves in water. Alkalis form OH-(aq) ions in water
The reaction between acids and bases is calkled neutralisation. Make sure you learn it:
acid + base --> salt + water
Neutralisation can also be seen in terms of H+ and OH- ions like this, so learn it too:
H+(aq) + OH-(aq) --> H20 (l)
When an acid neutralises a base (or vice versa), the products are neutral, i.e they have a pH of 7.
