In a chemical sense soap is a salt made up of a corboxylix acid and an alkali like sodium of potassium. This alkali-fat mixture is stirred until "trace". Unlike cold-processed soap, hot-processed soap can be used right away because the alkali and fat saponify more quickly at the higher temperatures used in hot-process soap making. Observations: The following outcomes were noticed at the end of the experiment. The test requires to be done with distilled water as well as with tap water.

Smaller amounts of unsaponifable oils and fats that do not yield soap are sometimes added for further benefits. ... Chemistry Projects. You can change your ad preferences anytime. The presence of such salts makes the water hard and the water is called hard water. Often, emollients such as jojoba oil or Shea butter are added 'at trace' (the point at which the saponification process is sufficiently advanced that the soap has begun to thicken), after most of the oils have saponified, so that they remain unreacted in the finished soap.

Procedure: 1. cbse sample papers for class 12 chemistry pdf examframe. Cold-process soap making takes place at a sufficient temperature to ensure the liquification of the fat being used. Whenever soap is applied on a dirty wet cloth, the non polar alkyl group dissolves in grease while the polar -COONa part dissolves in water. For example, olive oil provides mildness in soap; coconut oil provides lots of lather; while coconut and palm oils provide hardness. Soap can also be made of vegetable oils, such as palm oil, and the product is typically softer.
