NaOH is scientifically known as sodium hydroxide, and commercially known as caustic soda. It is made from the electrolosis of a salt water solution called brine in a manufacturing facility known as a chlor-alkali plant. Sea water could obviously be used, but would be weaker in concentration than the commercially prepared brine.
In any case, the brine flows in a trough over a running bed of liquid Mercury. Carbon rods are immersed in the brine and act as electrodes to carry a strong electrical current through the brine solution. This results in the salt (sodium chloride - NaCl) breaking down and releasing chlorine gas (Cl2), with the Na then picking up the hydroxyl radical (OH-) to become NaOH.
The reaction also produces a weak solution of sodium hypochlorite (NaOCl) a bleaching solution known commercially as Javex or Chlorox.

HOW TO 0.1N NaOH solution preparation?
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..
How do you prepare 30 percent of NaOH?
300g NaOH + 700g water
How to prepare 2N solution of NaOH in 10 ml of water?
we need 0.8gm NaoH and dissolved in 10 ml of water to make 2N solution of NaoH .
How do you prepare Diluted NaOH?
"Dilute NaOH" without any other specifications in a chemistry lab generally refers to a 6M solution of NaOH in water.
How can you prepare 300ml of 2.5M NaOH solution?
dissolve 100g in 300ml water

How can you prepare 300ml of 2.5M NaOH solution?
dissolve 100g in 300ml water
How will prepare 200ml of 10 percent NaOH Solution?
Dissolve 0.4 g of NaOH in 100 ml of water. Try it out. Actually it is not suitable to prepare NaOH solutions in standard flasks.It should be made in beakers & must be standardised..This is done to find the correct normality...
How do you prepare a 50 percent of NaOH solution?
Dissolve slowly 50 g NaOH in 100 mL water; advertisement: sodium hydroxide solution is dangerous !
How can we Prepare 1mM NaOH?
0,4 g NaOH + 1000 ml H2O
What amount of NaoH has to be added to 350ml of water to prepare 40normal solution?
560 g in 350 ml (But I am not sure if that large quantity of NaOH will dissolve in 350 ml of wate).
How do you prepare 0.25N of sodium hydroxide?
add 10 grams of NaoH into 1000 ml water, it will give you NaoH of 0.25N. As for making 1N solution you need to disolve 40 grams of NaoH into 1 litre water.
How do you prepare 0.5N NaOh?
Take half volume of 1.0 M NaOH and add another half volume of water. Or Take 20.0 gram NaOH , carefully dissolve this completely in ca. 0.9 L water and then fill up to 1.0 L end volume.
How do you prepare NaOH solution in laboratory?
