Solve numerical problems involving neutralisation
Neutralisation
6.7
Peneutralan
Definition of neutralisation
The reaction of an acid with base or alkali that forms salt and water
Some of the examples:
\(HCl + NaOH \rightarrow NaCl+H_2O\)
\(H_2SO_4 + CuO \rightarrow CuSO_4 + H_2O\)
\(2HNO_3 + Ca(OH)_2 \rightarrow Ca(NO_3)_2 + H_2O\)
Application of neutralisation in daily life
Field
Application
Industry
Calcium carbonate is used to remove acidic gas such as sulphur dioxide before it is released to the air.
Agriculture
Lime or calcium carbonate is used to neutralise acidic soil.
Health
Antacids and milk of magnesia are used to neutralise the excess hydrochloric acid in the stomachs of gastric patients.
Acid-base titration
Titration is a quantitative analysis that involves the gradual addition of acid into alkali.
This technique is used to measure the amount of acid needed to neutralise an amount of alkali.
Apparatus setup for titration
Acid-base indicators such as methyl orange and phenolphthalein are used to indicate the completion of the neutralisation.
The common indicators are as follows;
