Mg(C17H35COO)2 is formed, which is not water soluble. This is why detergents are often used instead of soaps in water containing magnesium or calcium ions - because no solids will form.
Soft water produces more lather when soap is added compared to hard water. Soft water has fewer minerals, such as calcium and magnesium, which can react with soap to form a scum that reduces lather production.
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.
To test for insoluble matter in soap, you can perform a simple solubility test by dissolving a small amount of the soap in water and observing if any residue remains. If there is residue, filter it out and dry it to determine the amount of insoluble matter present in the soap. The percentage of insoluble matter can then be calculated by dividing the weight of the residue by the initial weight of the soap sample and expressing it as a percentage.
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.
Rosin is added to soap-making because it helps improve the quality and lather of the soap. It also acts as a hardening agent, making the soap more stable and longer-lasting. Additionally, rosin can provide a pleasant aroma to the soap.
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.
Sodium chloride is added to precipitate the soap.
Sodium chloride is used to precipitate soaps from the solution.
Sodium chloride is added to increase the viscosity of the solution.
Compounds like sodium chloride (salt) or glycerin may be added to increase the weight of soap. These additives help to make the soap harder and increase its density, resulting in a heavier final product.
Sodium chloride help the precipitation of soaps.
Sodium chloride solution is added during soap processing to increase the hardness of the soap and help separate it from other components in the mixture. It also helps improve the clarity and texture of the soap by promoting proper saponification.
Any bath soap contain a little sodium chloride.
Sodium chloride is needed to precipitate soap from solutions.
Adding sodium chloride soap is precipitated.
Calcium chloride is a type of salt. When dissolved and mixed with soap, it will form a white film commonly known as soap scum.
If the soap is fully and completely water soluble, its chloride content can be precipitated by adding silver nitrate solution to the soap solution, and the amount of silver chloride solution used until precipitation ceases measures the content of sodium originally in the solution. There are also many other analytical methods available.
