The pH scale is a measure of the acidity or basicity (alkalinity) of a solution. It ranges from 0 to 14, with 7 being neutral, values less than 7 being acidic, and values greater than 7 being basic or alkaline.
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
12 Σεπ 2022 · The physiological pH of the human body is essential for many processes necessary to life, including oxygen delivery to tissues, correct protein structure, and innumerable biochemical reactions that rely on the normal pH to be in equilibrium and complete.
The molecular formula for ethanol is CH 3 CH 2 OH or C 2 H 5 OH. The shorthand formula is simply EtOH, which describes the ethane backbone with a hydroxyl group. The molecular formula describes the type and number of atoms of elements present in an ethanol molecule.
explain why the boiling points of alcohols and phenols are much higher than those of alkanes, ethers, etc., of similar molecular mass. discuss the factors that are believed to determine the acidity of alcohols and phenols.
