How Saponification Makes Soap - ThoughtCo

Aug 02, 2018·Types of Soaps . The saponification reaction may be tailored to produce different types of soaps: Hard Soap: Hard soap is made using sodium hydroxide (NaOH) or lye. Hard soaps are especially good cleansers in hard water that contains magnesium, chloride, and calcium ions.. Soft Soap: Soft soap is made using potassium hydroxide (KOH) rather than sodium hydroxide.

For 0.01 M titrant and assuming 50 mL burette, aliquot taken for titration should contain about 0.35-0.45 millimoles of magnesium and calcium together. Depending on the water hardness we may use more concentrated or ...

Saponification - Wikipedia

Saponification is a process that involves the conversion of fat, oil, or lipid, into soap and alcohol by the action of aqueous alkali (e.g. NaOH). Soaps are salts of fatty acids, which in turn are carboxylic acids with long carbon chains. A typical soap is sodium oleate. Saponification of fats. Vegetable oils and animal fats are the traditional materials that are saponified. These greasy ...

Determination of Hardness of Water by EDTA Titration method

Aug 23, 2017·In this article, we are going to talk about the determination of hardness of water by EDTA titration method.The causes of hardness of water is by multivalent metallic cations, which react with soap to form precipitates and with certain anions present in water to form scale.. The primary cations causing hardness are calcium, magnesium, strontium, ferrous ion, and manganous ions.

Saponification-The process of Making Soap (Theory) : Class ...

SOAP. Soaps are sodium or potassium salts of long chain fatty acids. When triglycerides in fat/oil react with aqueous NaOH or KOH, they are converted into soap and glycerol. This is called alkaline hydrolysis of esters. Since this reaction leads to the formation of soap, it is called the Saponification process.

Fatty Acids and Soap Making

One thing you may notice when reading my soap oil profile pages is that the percentage of fatty acids don't always add up to 100%. For instance, the fatty acid content of coconut oil is Lauric acid: 48%, Linoleic acid: 2%, Linolenic acid: 0%, Oleic acid: 8%, Palmitic acid: 9%, Ricinoleic acid: 0%, Stearic acid: 3%, and Myristic acid: 19%. If you took the time to add all this up, you would only ...

Soap. Soaps are cleaning agents that are usually made by reacting alkali (e.g., sodium hydroxide) with naturally occurring fat or fatty acids. The reaction produces sodium salts of these fatty acids, which improve the cleaning process by making water better able to lift away greasy stains from …

Water analysis-Determination of Chemical parameters ...

In a hard water sample, the total hardness can be determined by titrating the Ca 2+ and Mg 2+ present in an aliquot of the sample with Na 2 EDTA solution, using NH 4 Cl-NH 4 OH buffer solution of pH 10 and Eriochrome Black-T as the metal indicator.. Na 2 H 2 Y (Disodium EDTA solution) → 2Na + + H 2 Y-. Mg 2+ + HD 2- (blue) → MgD (wine red) + H +. D (metal-indicator complex, wine red colour ...

Water Hardness - Water Quality Parameter Overview | Hach

Hardness is a measure of the soap consuming capacity of water. The term comes from an expression of how difficult or "hard" it is to wash clothes with the water. When soap is mixed with hard water, the minerals combine with the soap and form a solid precipitate. This decreases the cleaning efficiency of the soap and forms soap scum.

Soap Qualities - SoapCalc

Hardness - This refers to the hardness of the soap bar. Higher is harder. A range of 29 to 54 is satisfactory for this soap quality. A low Iodine value also contributes to hardness (see below). Cleansing - This refers to the soap's ability to grab on to oils. A soap molecule is a chain of carbon atoms.
