The products of a saponification reaction are _____. a triglyceride and glycerola strong base and carboxylate saltsglycerol and carboxylate salts2. Triglycerides are esters derived from _____ glycerol molecule(s) and _____ fatty acids.one; twotwo; fourone; threetwo; three3. Triglycerides are generally composed of identical fatty acids. TrueFalse4. The nonpolar tail of a soap molecule is _____. hydrophilichydrophobichygroscopic

MicellesSurfactantsSudsScum6. _____ lower the surface tension of water.MicellesSurfactantsScums7. Soap molecules react with _____ ions to produce soap scum. Na+Caand Mg2+2+8. Detergents are produced by saponification. 9. Triglyceride composition of the oil used determines the consistency of the resulting soap.
Copyright 2021 - Science Interactive | Extension Questions10. Reactants in a saponification are stirred because they differ in _____. 11. Hard water _____ the amount of suds produced by soaps.decreasesincreasesdoes not affect12. Soaps and detergents both produce precipitates in hard water. TrueFalsethis compares to the reaction of saponification used with canola oil because you can use canola oil to make diesel fuel aswell. It has to do with the heating process that helps convert the triglycerides.1. Canola oil is a source of biodiesel fuel. Research how the triglycerides in canola oil are converted to diesel fueland compare this chemical reaction to the saponification reaction used with canola oil in this experiment.
