Take 10ml of 1N NaOH and dilute to 100ml with distilled water or take 0.4g of NaOH pellets and dissolve in 1000L distilled water.
to prepare 1N we have to dilute 40gms of NaOH in 1 litre of water as for NaOH normality =molarity so to prepare 0.1N NaOH we have to dilute 4gms of NaOH in 1 litre of water..

sodium hydroxide is prepared industrally by the electrolysis of brime but the lab. Preparation is sodium chloride and trioxosulphate(vi)acid.
This is an indication for the preparation of given standardized solution.
sodium hydroxide act as a catalyst
sht stains?

C2H3NaO2 + NaOH --> NaCO3 + CH4
This is an indication for the preparation of given standardized solution.
An example; preparation of sodium chloride in laboratory: NaOH + HCl = NaCl + H2O
4p+5o2->p4o10
4p+5o2->p4o10
NaOH it is a concentrated form of sodium hydroxide
