Protein fibers (wool and silk) will tolerate the absorption of a limited amount of mild acid, and cellulose will tolerate a certain degree of alkalinity; however, both can be destroyed by strong acids and alkalis. Strong acids and alkalis can also adversely affect dyes. What is most important is to maintain a pH level that ...How to Calculate PPM - Sciencing09.03.2020·You can perform a PPM conversion easily provided you have two quantities in the same unit (or that you can convert into the same unit) or a percentage value. PPM means "parts per million," so to calculate it you divide the amount of the solute by the total amount of solution, them multiply by 10^6.



Water Chemistry - Idaho State University

All these water molecules attracting each other mean they tend to clump together. This is why water drops are, in fact, drops! If is wasn't for some of Earth's forces, such as gravity, a drop of water would be ball shaped -- a perfect sphere. Even if it doesn't form a perfect sphere on Earth, we should be happy water is sticky. Water is called the "universal solvent" because it …

Classification and properties of matter - Chem1

This description of Ivory Soap is a classic example of junk science from the 19th century. Not only is the term "pure" meaningless when applied to an undefined mixture such as hand soap, but the implication that its ability to float is evidence of this purity is deceptive. The low density is achieved by beating air bubbles into it, actually reducing the "purity" of the product and, by diluting ...

Soap - Elmhurst University

Soap is a mixture of sodium salts of various naturally occurring fatty acids. Air bubbles added to a molten soap will decrease the density of the soap and thus it will float on water. If the fatty acid salt has potassium rather than sodium, a softer lather is the result. Soap is produced by a saponification or basic hydrolysis reaction of a fat or oil. Currently, sodium carbonate or sodium ...

The Decomposition of Hydrogen Peroxide | The Chemistry Blog

Hydrogen peroxide has a finite shelf-life because, over time, it naturally decomposes into water and oxygen gas. Although this will take a while, UV rays from sunlight as well as warm conditions can actually catalyse the decomposition reaction. This is why hydrogen peroxide is generally stored in dark plastic containers.
