k H CO 2 is a constant including the solubility of carbon dioxide in blood. k H CO 2 is approximately 0.03 (mmol/L)/mmHg; p CO 2 is the partial pressure of carbon dioxide in the blood; Combining these equations results in the following equation relating the pH of blood to the concentration of bicarbonate and the partial pressure of carbon ...
Sodium hydroxide can form several hydrates NaOH·nH 2 O, which result in a complex solubility diagram that was described in detail by Spencer Umfreville Pickering in 1893. [18] The known hydrates and the approximate ranges of temperature and concentration (mass percent of NaOH) of their saturated water solutions are: [ 13 ]
Aqueous carbon dioxide reacts with water to form carbonic acid which is very unstable and will dissociate rapidly into hydronium and bicarbonate. Therefore, in seawater, dissolved inorganic carbon is commonly referred to as the collection of bicarbonate, carbonate ions, and dissolved carbon dioxide (CO 2, H 2 CO 3, HCO − 3, CO 2− 3).

Partition coefficients can be measured experimentally in various ways (by shake-flask, HPLC, etc.) or estimated by calculation based on a variety of methods (fragment-based, atom-based, etc.). If a substance is present as several chemical species in the partition system due to association or dissociation, each species is assigned its own K ow ...
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.
Here, 1 / f eq can have a fractional (non-integer) value. In precipitation reactions, the equivalence factor measures the number of ions which will precipitate in a given reaction. Here, 1 / f eq is an integer value. Normal concentration of an ionic solution is also related to conductivity (electrolytic) through the use of ...
In thermodynamics, an activity coefficient is a factor used to account for deviation of a mixture of chemical substances from ideal behaviour. [1] In an ideal mixture, the microscopic interactions between each pair of chemical species are the same (or macroscopically equivalent, the enthalpy change of solution and volume variation in mixing is zero) and, as a result, properties of the mixtures ...
