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.

In hard water we find Calcium and Magnesium ions. These react with the Sodium stearate (soap) to form Calcium and magnesium stearate and Na+ ions Sodium stearate+ Ca2+ +Mg2+ --> Calcium stearate + Magnesium stearate + Na+ ions
Calcium stearate is carboxylate of calcium that is found in some lubricants and surfactants. It is a white waxy powder. It is produced by heating stearic acid, a fatty acid, and calcium oxide. It is also formed when sodium stearate is added to hard water (as scum). Sodium stearate + CaSO4 -----> C36H70CaO4 + Na2SO4 OR Sodium stearate + Ca(HCO3)2-------------> C36H70CaO4 + NaHCO3 Anyway, just wanted to refresh your memory a little bit... The formula is, as mentioned earlier : C36H70CaO4 Oh, and sodium stearate's just a fancy word for soap...
The structural formula for sodium stearate, which is a type of soap, is CH3(CH2)16COONa. This formula represents the sodium salt of stearic acid, which is a long-chain fatty acid commonly found in soap formulations.
Soap is primarily sodium stearate. It leaves a film when it combines with hard water to form calcium stearate (soap scum). Body wash is a detergent that does not form soap scum. It, like Zest bath bars has no sodium stearate. The difference between the Zest and most body washes is the fragrance in the recipe and that you are paying for a whole lot of water and a fancy bottle.
One advantage is that detergents do not react with hard water to form soap scum (Calcium stearate) like soap does.
To remove sodium chloride from calcium stearate, you can dissolve the mixture in water. Sodium chloride is water-soluble, so it will dissolve in the water while calcium stearate remains insoluble. By filtering the solution, you can separate the sodium chloride from the calcium stearate.
The ratio of Ca2+ ions to stearate anions depends on the specific compound or salt being referred to. For example, in calcium stearate (Ca(C17H35COO)2), the ratio is 1:2, with one Ca2+ ion for every two stearate anions. However, in other compounds, such as calcium di(stearate) (Ca(C17H35COO)2), the ratio may vary.
Calcium chloride is a type of salt. When dissolved and mixed with soap, it will form a white film commonly known as soap scum.
When soaps are dissolved in hard water, a scum is formed due to the reaction between the soap molecules and the calcium and magnesium ions present in the water. The reaction forms insoluble calcium and magnesium salts of the fatty acids in the soap, which precipitate out as a scum. This scum is difficult to dissolve in water and can cling to surfaces, causing the typical "soap scum" seen in hard water environments.
The balanced chemical equation for the reaction between calcium chloride (CaCl2) and sodium stearate (C17H35COONa) would be: 2 CaCl2 + 2 C17H35COONa -> 2 NaCl + Ca(C17H35COO)2 This equation shows that calcium chloride reacts with sodium stearate to produce sodium chloride (NaCl) and calcium stearate.
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.
