Neutralisation (2)

Not quite remember

I easily remember

Applications of neutralisation in daily life (2)

Weak alkali in the shampoo neutralises acid on hair

Applications of neutralisation in daily life (3)

Toothpaste contains a base that neutralises lactic acid produced by bacteria in our mouth

Applications of neutralisation in daily life (4)

Slaked lime, Ca(OH)2 which is alkaline, is used to treat acidic soil

Applications of neutralisation in daily life (4)

Neutralisation reaction is also applied in the production of fertilisers such as urea, potassium sulphate, K2SO4, ammonium nitrate, NH4NO3 and others

Urea production process

Urea can be produced from the neutralisation reaction between ammonia, NH3 and carbon dioxide, CO2

Titration Method (1)

Is a quantitative analysis method to determine the volume of acid needed to completely neutralise a given volume of alkali and vice versa

Titration Method (2)

In acid-base titration, a solution of known concentration is slowly added from a burette into a conical flask that contains a volume of alkali of unknown concentration

Titration Method (3)

Titration stops as soon as the acid-base indicator changes colou

Titration Method (4)

The point in the titration at which the acid-base indicator changes colour is known as the end point

Titration Method (5)

The end point of the neutralisation process can be determined when the acid-base indicator changes colour
