Meaning of neutralisation
The reaction of acids with alkalis (bases) to produce salt and water only

Reactants

Products
General equation
Acid + Alkali -> Salt + Water
Applications of neutralisation in daily life
Medicine - Milk of magnesia Hair health - shampoo Dental health - toothpaste
Titration method
Quantitative analysis method to determine the volume of acid needed to completely neutralise a given volume of alkali
Indicator and colour in medium
Phenolphthalein - colourless Methyl orange - orange
Neutralisation (1)
In the reaction, the salt and water produced are neutral because the acid lose its acidity and the alkali lose its alkalinity
Neutralisation (2)
The neutralisation reaction between nitric acid, HNO3 with potassium hydroxide, KOH to produce potassium nitrate solution, KNO3 and water, H2O
Neutralisation (3)
In neutralisation, the actual reaction that occurs only involves the combination of hydrogen ions, H+, from the acid and the hydroxide ions, OH– from the alkali to produce water molecules, H2O
Applications of neutralisation in daily life (1)
Milk of magnesia Mg(OH)2 relieves gastric pain by neutralising the excessive hydrochloric acid in the stomach
