Analysis:

Titration method:

50 ml sample. Add a pinch of sodium thiosulphate crystals. Add a few drops of methyl orange.
Titrate with 0.5 N HCl until the colour changes from yellow to orange-red.
The percentage of Chemipro Caustic is equal to the number of millilitres of 0.5 N HCl times the titration factor of
0.08
