Question

Answer

Making Soap Containing Sodium Salt

Heating NaOH with glyceryl ester of fatty acid results in the production of soap containing sodium salt.

Explanation:

- Soap is made by a process called saponification, where an alkali (such as NaOH) is reacted with a fat or oil to produce soap and glycerol.
- The glyceryl ester of fatty acid (also known as triglycerides) is a type of fat that is commonly used in soap making.
- When NaOH is added to the glyceryl ester of fatty acid, the ester bond in the fat is broken, releasing the fatty acids and glycerol.
- The sodium ions in the NaOH then react with the fatty acids to form sodium salts (i.e. soap).
- The glycerol, which is also produced during the reaction, can be further processed for use in other industries.

Therefore, option B is the correct answer as heating NaOH with glyceryl ester of fatty acid results in the production of soap containing sodium salt.

Answer

Soap is a mixture of sodium salts of various naturally occurring fatty acids. Air bubbles added to a molten soap will decrease the density of the soap and thus it will float on water. If the fatty acid salt has potassium rather than sodium, a softer lather is the result. Soap is produced by a saponification or basic hydrolysis reaction of a fat or oil. Currently, sodium carbonate or sodium hydroxide is used to neutralize the fatty acid and convert it to the salt.
General overall hydrolysis reaction:
fat + NaOH → glycerol + sodium salt of fatty acid

Answer

Vegetable oils and animal fats are the traditional materials that are saponified. These greasy materials, triesters called triglycerides, are mixtures derived from diverse fatty acids. Triglycerides can be converted to soap in either a one- or a two-step process. In the traditional one-step process, the triglyceride is treated with a strong base (e.g., lye), which cleaves the ester bond, releasing fatty acid salts (soaps) and glycerol. This process is also the main industrial method for producing glycerol. In some soap-making, the glycerol is left in the soap. If necessary, soaps may be precipitatedby salting it out with sodium chlorideFat in a corpse converts into adipocere, often called 'grave wax'. This process is more common where the amount of fatty tissue is high and the agents of decomposition are absent or only minutely present.
