How to calculate sodium hydroxide solution percentage by titrimetry?

Answer 1

This process is done in titration.NaOH(sodium hydroxide) is a base, phenolphthalein is added and the base turns pink in colour.After titrating out the base by any acid ( drop by drop from the burette) the base gets colourless again.Titration should be in very cautious way, a single drop difference could spoil your whole experiment
