Saponification: Sodium Hydroxide and Soap

solubility in water. Other raw materials: * Builders These are essentially used to build up soaps. Examples of alkali builders are sodium carbonate, sodium silicate and sodium sulfate. * Fillers Fillers increase the bulk of soap by adding weight, thus reducing the production cost. Clay, kaolin, talc, starch, common salt, chalk and magnesium carbonate are the most commonly used fillers in soap making. * Common salt (Brine) It is used to separate out glycerin and excess caustic from...

Quantitative Analysis of Soda Ash by Double-Indicator Titration

detergent manufacture, water treatment etc. It can be a pure compound of sodium carbonate, sodium bicarbonate or sodium hydroxide or the mixture of the three with compatible percent compositions. These compositions are determined by acid-base titrations, a volumetric process in determining the concentration of a substance in a certain solution which uses a base or acid as the titrant. The reaction between sodium carbonate and hydrochloric acid occurs in 2 stages, with the formation of bicarbonate...

Photosynthesis Experiment

environment. Glucose, as a product is used to make energy for growth. Lastly, the oxygen is a waste product in this chemical reaction, which become part of the Earth’s atmosphere. At this experiment, carbon dioxide and water were replaced by ‘Sodium hydrogen carbonate’ because this led to simpler procedures than using carbon dioxide and water separately. During photosynthesis, leaves only accept certain wavelength of light. For instance, most of leaves reflects radiation and receive blue and red colours...

Periodic Table and Sodium

Sodium, one of many elements in the periodic table is being used in everyday life, it is also an essential element within your body. It is just another element, but one of the differences is that this element is something that most people consume every day. Sodium has played an important role in everyday life because of its uses in medicine, industry, and agriculture(Shriver). Sodium was discovered in 1807 by a man named Sir Humphrey Davy. He was well known for his discoveries of most alkali metals...
