Note on Soap

Soaps are mixtures of sodium salts of higher fatty acids(palmitic, stearic & oleic acids). It is used for washing clothes, to remove dirt & oil or grease by forming emulsions with water.

Calculation For Total Fatty Matter Of Soap

The experiment related to Total Fatty Matter of soap is written in the previous post.

Calculation of TFM is as follows:

• Weight of conical flask + soap( after drying)


• Weight of conical flask alone


• Initial weight of soap taken


• TFM = (Weight of conical flask + soap (after drying)- Weight of conical flask alone)/Initial weight of soap taken)*100
