1)Explain the process of saponification. What reacts with what to produce what?

2. Biodiesel can be made from plant oils in a transesterification reaction. How does making biodiesel in this way differ from the saponification reaction you used to make your soap?

3. A soap’s ability to form suds (bubbles) is one indicator of how effective it will be at cleaning things. Based on how “sudsy” your samples were, rank the soaps you make and worked with in order of how effective they would be.

4. You may have noticed a precipitate formed when you added calcium ions to one or more of your soap samples. Why did this happen?

Expert Solution

Ans-1- Saponification is simply the process of making soaps. Soaps are just potassium or sodium salts of long-chain fatty acids. During saponification, ester reacts with an inorganic base to produce alcohol and soap.

Generally, it occurs when triglycerides are reacted with potassium or sodium hydroxide (lye) to produce glycerol and fatty acid salt, called ‘soap’.

Saponification Reaction

Triglycerides are generally animal fats and vegetable oils. When they are reacted with sodium hydroxide, a hard form of soap is created. This is where potassium comes and creates a softer version of the soap.

The equation can be written as:

Ester + Base —–> Alcohol + Soap

General reaction of soap

so ester react with base to form soap (carboxylate ion) and alcohol

21. In the Haber - Bosch process, hydrogen gas reacts with nitrogen gas to produce ammonia according to the following equation 3 H 2 (g) + N 2 (g) → 2 NH 3 (g) The production of ammonia is difficult and often results in lower yields than those predicted from the chemical equation. For instance, if 1.36 g of hydrogen gas are allowed to react with 9.97 g of nitrogen gas, 2.24 g of ammonia are produced. What is the...
