Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M).
8 - 12 it is in equilibrium with the One explanation for why phenol is more acidic than aliphatic compounds containing an -OH group is Aqueous solutions of phenol are weakly acidic and turn blue litmus slightly to red. Phenol, 4-(2-phenyl diazenyl)-[ACD/Index Name] ... Molar Volume: 175.4±7.0 cm 3: Predicted data is generated using the US Environmental Protection Agency’s EPISuite ™ Log Octanol-Water Partition Coef (SRC): Log Kow (KOWWIN v1.67 estimate) = 3.63 Boiling Pt, Melting Pt, Vapor Pressure Estimations (MPBPWIN v1.42): Boiling Pt (deg C): 335.14 (Adapted Stein & Brown … The sodium salt of phenol, sodium phenoxide, is far more water-soluble. We use the most common isotopes. These relative weights computed from the chemical equation are sometimes called equation weights.If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight.

Wiley-Interscience, New York. It was a remarkable achievement Almost one in every two patients died. molar mass and molecular weight Part One: Raw Materials and Manufacture. When he checked the wound, Lister was pleasantly surprised to find no signs of infection, just redness near the edges of the wound from mild burning by the carbolic acid. Phenol is a weak acid. Industrial Organic Chemicals in Perspective. Before antiseptic operations were introduced at the hospital, there were sixteen deaths in thirty-five surgical cases. For the group of chemicals containing a phenol group, see "Carbolic acid" redirects here. The toxic effect of phenol on the central nervous system, discussed below, causes sudden collapse and loss of consciousness in both humans and animals; a state of cramping precedes these symptoms because of the motor activity controlled by the central nervous system.Phenol is a normal metabolic product, excreted in quantities up to 40 mg/L in human urine.Phenol is a measurable component in the aroma and taste of the distinctive Phenol and its vapors are corrosive to the eyes, the skin, and the respiratory tract.Since phenol is absorbed through the skin relatively quickly, systemic poisoning can occur in addition to the local caustic burns.This article is about the molecule.
Because of phenol's commercial importance, many methods have been developed for its production, but only the cumene process is the dominant technology. Molar mass of C6H5OH = 94.11124 g/mol. Molecular weight calculation: 12.0107*6 + 1.00794*5 + 15.9994 + 1.00794 ›› Percent composition by element. He theorized that if germs could be killed or prevented, no infection would occur. The major uses of phenol, consuming two thirds of its production, involve its conversion to precursors for plastics. Acidity.
Computing molecular weight (molecular mass) To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets. Lister reasoned that a chemical could be used to destroy the micro-organisms that cause infection.Meanwhile, in Carlisle, England, officials were experimenting with a sewage treatment, using carbolic acid to reduce the smell of sewage cess pools.
Phenol is neutralized by When phenol reacts with iron(III) chloride solution, an intense violet-purple solution is formed. Having heard of these developments and having himself previously experimented with other chemicals for antiseptic purposes without much success, Lister decided to try carbolic acid as a wound antiseptic. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. Dietland Muller-Schwarze, 2003, page 43 (World Health Organization/International Labour Organization: International Chemical Safety Cards,
For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.Calculate the molecular weight Phenol is also a versatile precursor to a large collection of drugs, most notably Phenol was once widely used as an antiseptic, its use pioneered by Joseph Lister (see From the early 1900s to the 1970s it was used in the production of Phenol spray, usually at 1.4% phenol as an active ingredient, is used medically to help sore throat.Phenol is so inexpensive that it attracts many small-scale uses.
