In chemistry, an alcohol (from Arabic الكحل (al-kuḥl) ' kohl '), [2] is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom. [3][4] Alcohols range from the simple, like methanol and ethanol, to complex, like sugars and cholesterol. The presence of an OH group ...
Data obtained from Lange's Handbook of Chemistry, 10th ed. and CRC Handbook of Chemistry and Physics 44th ed. The annotation, d a °C/ b °C, indicates density of solution at temperature a divided by density of pure water at temperature b known as specific gravity. When temperature b is 4 °C, density of water is 0.999972 g/mL. % wt. methanol.
The solution was initially prepared at 20 °C and then stored for 2 days at 4 °C. In chemistry, solubility is the ability of a substance, the solute, to form a solution with another substance, the solvent. Insolubility is the opposite property, the inability of the solute to form such a solution. The extent of the solubility of a substance in ...
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 ...
Acidified solution of potassium dichromate. The concentration of ethanol in a sample can be determined by back titration with acidified potassium dichromate. Reacting the sample with an excess of potassium dichromate, all ethanol is oxidized to acetic acid: CH 3 CH 2 OH + 2[O] → CH 3 COOH + H 2 O
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Properties of aqueous ethanol solutions. Data obtained from Lange 1967. Mass fraction, %. Volume concentration, %. Mass concentration, g/ (100 ml) at 15.56 °C. Density relative to 4 °C water [citation needed] Density at 20 °C relative to 20 °C water.
Solubility table. The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/ (100 mL)), unless shown otherwise.
