How you can made calcium soap of fatty acids?
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 4 compounds make up base grease?
The 4 compounds that make up base grease are mineral oil, lithium soap, calcium soap, and aluminum complex. These compounds work together to provide lubrication and enhance the grease's performance.
Soap scum physical or chemical change?
A chemical change. Soap scum is usually found in 'hard' water areas, where there is a lot of calcium cations (Ca^(2+)). On dissolution of soap in water , the oily anion of soap combines with calcium cation , to form calcium sterate (The Scum).
What creates soap scum?
Most soaps contain sodium and potassium salts of fatty acids. These are water soluble compounds that help carry away oils and other water insoluble substances. Soap scum forms when these salts react with calcium and magnesium compound in the water. The newly formed calcium and magnesium salts are insoluble in water,and so forma coating on surfaces. This is more likely to happen if you have hard water, water rich in calcium and magnesium.
What type of water does soap lather the most?
Soap lathers the most in soft water, which has a low concentration of minerals like calcium and magnesium. Hard water, which has high mineral content, can interfere with the lathering ability of soap by forming insoluble salts.
How you can made calcium soap of fatty acids?

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.
How do you separate water from soap?
calcium carbonate can be added to soap water. caco3 reacts with soap and forms calcium sterate which can be filter from water.
Why is soap soluble in the presence of sodium ions but not calcium ions?
Nearly all sodium salts are soluble in water. Most calcium salts aren't. calcium salts of the same fatty acids that make up potassium and sodium soaps are not water soluble. Dissolved calcium and magnesium are the two most common minerals that make water "hard." The degree of hardness becomes greater as the calcium and magnesium content increases. Bathing with soap in hard water leaves a film of sticky soap curd on the skin
Reaction of soap with dissolved calcium chloride?
Calcium chloride is a type of salt. When dissolved and mixed with soap, it will form a white film commonly known as soap scum.
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.
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.
Why is Calcium chloride solution for soap?
Calcium chloride solution is often used in soap making because it acts as a firming agent, helping to enhance the texture and stability of the final product. It can also assist in the saponification process by providing additional calcium ions, which can improve the hardness of the soap. Additionally, calcium chloride can help in reducing the water content, leading to a longer-lasting bar of soap. Overall, it contributes to both the physical properties and quality of the soap.

Write the reactions of hard water with soap which leads to the formation of white insoluble scum?
When hard water reacts with soap, it forms an insoluble scum due to the reaction between the calcium and magnesium ions present in the water with the soap. The calcium and magnesium ions react with the soap molecules to form calcium and magnesium salts of the fatty acids, which are insoluble and appear as white scum in the water.
How is soap scum formed?
In water that contains a lot of calcium ions (Ca^(2+)), these ion combine with the stearate/palmate anion of soap, to form calcium palmate or calcium stearate (scum). NB Water that contains a lot of calcium ions is often known as 'hard water'. because it is difficult for soap to lather.
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.
