Sodium Hydroxide : Class - 10
Formula , preparation by electrolysis , common name and step by step reactions and its properties.
- Chemical formula of sodium hydroxide is NaOH
- It is also known as Caustic SodaÂ
- it is a strong baseÂ
Preparation :-Â
- it is obtained by the electrolytic decomposition of solution of sodium chloride(brine solution). sodium chloride decompose to form sodium hydroxide.
- in this process chlorine gas is obtained at anode and hydrogen gas is obtained at cathode this process is known as chlor alkali process.
At Cathode(gain of electron : Reduction)
At Anode(Loss of electron : Oxidation)
- Aqueous Solution of sodium chloride is known as brine solution.
