Best Answer

Soap scum is calcium soap of fatty acids.

It is the result of soap in hard water-- the fatty acids in soap bond with the calcium ions in hard water and create an insoluble compound.

Calcium soap of fatty acids can be made by reacting calcium hydroxide with a mixture of fatty acids derived from oils or fats. This process typically involves heating the fatty acid mixture with calcium hydroxide until a soap is formed. The calcium soap can then be separated and purified for use in various applications.

What type of fatty acids are used in soap?

In soap making, a combination of saturated and unsaturated fatty acids are used. Common fatty acids include lauric acid, stearic acid, oleic acid, and linoleic acid. The specific types of fatty acids used can vary depending on the desired properties of the soap.


How does soap react with the salts CaCl2 or MgCl2?

An insoluble salt is formed--commonly called soap scum. Soap is the potassium or sodium salt of fatty acids. When calcium takes the place of the sodium or potassium, a calcium salt is formed. This takes the form of a whitish precipitate.


How do you make calcium soap?

Calcium soap is typically made by reacting a fatty acid with calcium hydroxide, which is a base. The reaction results in the formation of calcium soap and glycerol, which is a byproduct. The calcium soap is then separated and purified for various uses, such as in lubricants or cosmetics.


What happens when calcium chloride is added to a soap that lathered most?

When calcium chloride is added to a soap that lathered well, it can form insoluble calcium salts with the fatty acids in the soap. This can reduce the effectiveness of the soap by decreasing its ability to form lather and clean effectively.


Which chamical is used to make soap?

Soaps are water-soluble sodium or potassium salts of fatty acids. It's made from fats and oils, or their fatty acids, by treating them chemically with a strong alkali.


Why hard water consumes a lot of soap?

The calcium (as calcium carbonate) in hard water replaces the sodium on the fatty acids of the soap causing them to precipitate as a sticky scum. This deposits soap scum on the things being washed and causes the formation of "bathtub ring" on bathtubs, sinks, etc.


What acid is in soap?

Soap often contains fatty acids such as oleic acid, palmitic acid, and stearic acid. These acids are the result of the saponification process, where fats and oils are combined with sodium hydroxide (lye) to produce soap.

Is calcium stearate a soap or a salt?

Soaps are usually salts of long chain fatty acids with Sodium or Potassium ion and are soluble in water but Calcium stearate is very slightly soluble in water so can not be used as soap so it is better to consider it as a salt only.


Is calcium stearate considered a soap or a salt?

What is soap a micture or a element?

Soap is a mixture composed of fatty acids, oils, and alkalis such as sodium hydroxide. It is not considered an element because it is made up of multiple different compounds.
