  1. Soap is made by triacylglycerols (also known as triglycerols) reacting with base (usually either potassium hydroxide – KOH or sodium hydroxide).
    Essentially, base-catalyzed ester hydrolysis occurs. First a nucleophilic substitution happens, then an acid-base reaction.
    Heat 1 mol of the fat (some number of acyl groups on a glycerol molecule) to some number of hydroxide moles (the same number as the number of acyl groups on the fat). It would help to know how many acyl groups were on your fat molecules, but if you’re in doubt, just add excess base and you should get higher yield. It should not harm your product, because the soap needs to be basic in order to separate easily from the glycerol product molecules. It may help to separate the charged soap molecules by adding sodium chloride, which will cause ionic bonding to occur (basically sodium-soap compound) which can precipitate (if any water is present in this reaction, precipitation will not occur because the ions will be soluble).

    Don’t get them mixed up!!!

  3. invent a new flavor of ice cream. . maybe HCl flavor or NaCl flavor . . you’ll get a perfect score in originality

  4. To make the ice cream freeze faster, you will need to add alot of salt to the ice and water. For soap, add perfume.
