The acid dissociation constant K < sub > a </ sub > is generally used in the context of acid-base reactions.

The numerical value of K < sub > a </ sub > is equal to the concentration of the products divided by the concentration of the reactants, where the reactant is the acid ( HA ) and the products are the conjugate base and H < sup >+</ sup >.

The stronger of two acids will have a higher K < sub > a </ sub > than the weaker acid ; the ratio of hydrogen ions to acid will be higher for the stronger acid as the stronger acid has a greater tendency to lose its proton.

Because the range of possible values for K < sub > a </ sub > spans many orders of magnitude, a more manageable constant, pK < sub > a </ sub > is more frequently used, where pK < sub > a </ sub >

If K is a number field, its ring of integers is the subring of algebraic integers in K, and is frequently denoted as O < sub > K </ sub >.

Theorem: If K < sub > 1 </ sub > and K < sub > 2 </ sub > are the complexity functions relative to description languages L < sub > 1 </ sub > and L < sub > 2 </ sub >, then there is a constant c – which depends only on the languages L < sub > 1 </ sub > and L < sub > 2 </ sub > chosen – such that

More generally, compact sets can be separated by open sets: if K < sub > 1 </ sub > and K < sub > 2 </ sub > are compact and disjoint, there exist disjoint open sets U < sub > 1 </ sub > and U < sub > 2 </ sub > such that and.

Until about 2000, users of Unix desktops regarded CDE as the de facto standard, but at that time, other desktop environments such as GNOME and K Desktop Environment 2 were quickly becoming mature, and became almost universal on the Linux platform, which already had a larger user base than most commercial Unixes in total.

This will yield a polytrope of index 3, which will have a total mass, M < sub > limit </ sub > say, depending only on < var > K </ var >< sub > 2 </ sub >.

Color temperatures over are called cool colors ( blueish white ), while lower color temperatures ( 2, 700 – 3, 000 K ) are called warm colors ( yellowish white through red ).

The CMBR has a thermal black body spectrum at a temperature of 2. 725 K, which peaks at the microwave range frequency of 160. 2 GHz, corresponding to a 1. 873 mm wavelength.

This results in constitutive cAMP production, which in turn leads to secretion of H < sub > 2 </ sub > O, Na < sup >+</ sup >, K < sup >+</ sup >, Cl < sup >−</ sup >, and HCO < sub > 3 </ sub >< sup >−</ sup > into the lumen of the small intestine and rapid dehydration.

The campaign strategy, dubbed " K < sub > 1 </ sub > C < sub > 2 </ sub >", was to focus on attacking the Truman and Roosevelt administrations on three issues: Korea, Communism and corruption.

One reason for the popularity of the dissociation constant in biochemistry and pharmacology is that in the frequently encountered case where x = y = 1, K < sub > d </ sub > has a simple physical interpretation: when = K < sub > d </ sub >, = or equivalently /(+)= 1 / 2.

Church, Ministry and Sacraments in the New Testament Paternoster Press: 1993, p. 92f </ ref > Moving on to Ignatius of Antioch, Barrett states that here we find a sharp distinction between ' presbyter ' and ' bishop ': the latter now stands out as " an isolated figure " who is to be obeyed and without whom it is not lawful to baptise or hold a love-feast .< Barrett, C.

μ < sub > vap </ sub >( T, p ), which are sufficient to determine the two variables T and p. In the diagram for CO < sub > 2 </ sub > the triple point is the point at which the solid, liquid and gas phases come together, at 5. 2 bar and 217 K. It is also possible for other sets of phases to form a triple point, for example in the water system there is a triple point where ice I, ice III and liquid can coexist.

Another style was to truncate the last 3 digits and append K, essentially using K as a decimal prefix similar to SI, but always truncating to the next lower whole number instead of rounding to the nearest.
