[1] [2] [3] It is defined as the number of millilitres (mL) of pure ethanol present in 100 mL (3.5 imp fl oz; 3.4 US fl oz) of solution at 20 °C (68 °F). The number of millilitres of pure ethanol is the mass of the ethanol divided by its density at 20 °C (68 °F), which is 0.78945 g/mL (0.82353 oz/US fl oz; 0.79122 oz/imp fl oz; 0.45633 oz ...
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
In titrations, the concentration of analyte in solution can be determined by titrating the standard solution against the analyte solution to determine the threshold of neutralization. [9] For example, to calculate the concentration of hydrogen chloride, a standard solution of known concentration, such as 0.5 M sodium hydroxide, is titrated ...
If one begins with a solution of 1 mol/L of a substance, the dilution required to reduce the number of molecules to less than one per litre is 1 part in 1×10 24 (24X or 12C) since: 6.02×10 23 /1×10 24 = 0.6 molecules per litre
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.
Psilocybin, also known as 4-phosphoryloxy-N,N-dimethyltryptamine (4-PO-DMT) [a] is a naturally occurring psychedelic compound produced by more than 200 species of mushrooms. [18] Effects include euphoria, hallucinations, changes in perception, a distorted sense of time, [23] and perceived spiritual experiences.
A bottle of colored liquid labelled as a love potion A collection of vials labelled as potions. A potion is a liquid "that contains medicine, poison, or something that is supposed to have magic powers." [1] It derives from the Latin word potio which refers to a drink or the act of drinking. [2]
The molar ionic strength, I, of a solution is a function of the concentration of all ions present in that solution. [3]= = where one half is because we are including both cations and anions, c i is the molar concentration of ion i (M, mol/L), z i is the charge number of that ion, and the sum is taken over all ions in the solution.
