Determination Of Total Alkali As Na2O in Washing Soap

AIM:
To determine the total alkali as Na₂O in the given sample of sunlight bar soap.
REAGENTS:

• Methyl orange indicator
• Distilled water: 30ml
• N/2 Standard HCl

APPARATUS:

• Conical flask
• Water bath
• Burette
• Electronic balance

PROCEDURE:

• Weigh accurately 10gm of the sliced soap sample using an electronic balance.
• Note the weight taken.
• Put the weighed sample into a clean conical flask.
• Add 30ml distilled water.
• Gently warm on a water bath to dissolve all the soap particle.
• Cool for a while.
• Titrate against N/2 std HCl from the burette using methyl orange as indicator.

CALCULATION:

Total alkali content as Na₂O = (Volume of HCl * Normality of HCl *3.1)/weight of the sample.

RESULT:

I was able to calculate the total alkali content as Na₂O in sunlight bar soap as 0.669 by taking 5gm of the sample.
