How do you remove sodium chloride from calcium stearate?
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.
Can chalk dissolve in HCl and why?
No, chalk (calcium carbonate) does not dissolve in hydrochloric acid (HCl) because calcium carbonate is insoluble in acids. When HCl is added to chalk, it will react with the calcium carbonate to form calcium chloride, water, and carbon dioxide gas, but the chalk itself will not dissolve.
What is balanced chemical equation for calcium chloride and sodium stearate?
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.
What is the chemical formula for Calcium Stearate?
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...
Will hcl dissolve silver?
No, hydrochloric acid (HCl) will not dissolve silver. Silver is resistant to corrosion by most acids, including HCl.

How calcium stearate is prepared?
Calcium stearate is typically prepared by reacting stearic acid with calcium hydroxide to form calcium stearate and water. The reaction is carried out at elevated temperatures with stirring to ensure complete conversion of the raw materials. The resulting calcium stearate can then be purified and dried for use in various applications.
What is the balance equation of calcium oxide and stearic acid?
Calcium oxide + Stearic Acid = Calcium Stearate + Water CaO + 2C18H36OOH = (C18H36OO)2Ca + H2O NB CAlcium stearate is the 'scum' that can appear on the side of a bath, when washing in 'hard' water.
The properties and application of calcium dodecyl stearate?
Calcium dodecyl stearate is a flaky or needle-like crystal chemical substance with a melting point of 82-93°C. Flammable and low toxicity. Insoluble in water, soluble in ethanol, ether and chloroform. The main use of calcium dodecyl stearate: widely used in lubricants, stabilizers, plastics and rubber additives. Calcium lauryl stearate is used as a lubricant and release agent for constant temperature and various plastic processing, and is an excellent rubber and plastic additive. Calcium dodecyl stearate is also used in organic synthesis.
Will hcl dissolve silver?
No, hydrochloric acid (HCl) will not dissolve silver. Silver is resistant to corrosion by most acids, including HCl.
What is the ratio of Ca2 and stearate anion?
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.
Is calcium sulfate hcl insoluble?
Calcium sulfate is generally insoluble in water, meaning it does not readily dissolve in water. However, the solubility of calcium sulfate can be affected by factors such as temperature and the presence of other chemicals.
Does hcl dissolve diamonds?
No, hydrochloric acid (HCl) does not dissolve diamonds. Diamonds are the hardest known natural material and are resistant to most chemicals, including acids like HCl.
What is purpose of adding HCl to the CaCO3 -H2O mixture prior to dilute?
Adding HCl to the CaCO3 - H2O mixture prior to dilution helps dissolve the calcium carbonate by reacting with it to form calcium chloride, water, and carbon dioxide. This step is done to increase the solubility of calcium carbonate and facilitate its removal in subsequent steps.
