Neutralisation : the reaction between Acids & Bases ...
acid + base --> salt + water
H+ + OH - --> H2O (l)
When an acid neutrilises a base (or vice versa), the prouducts are neutral, i.e they have a PH of 7 .
The real life examples of neutrilisation :
-indigestion is caused by too much hydrochloric acid in the stomach. Indigestion tablets contain bases such as magnesium oxide; which neutralises the excess.
-Fields with acidic soils can be improved by adding lime . Lime is calcium hydroxide Ca(oH)2 which ofcourse is an alkali.
Lakes affected by rain can also be neutralised by adding lime. fishes are saved :)
