We're going to start with the simplest possible scenario, which is that pH is equal to pK_a. When pH is equal to pK_a, we're raising 10 to the zeroth power. So anything to the zeroth power is equal to one. Which tells us that this ratio is equal to one. bogleheads apple podcast

"WebDec 30, 2024 · The pKa measures how tightly a proton is held by a Bronsted acid. A pKa may be a small, negative number, such as -3 or -5. It may be a larger, positive number, such as 30 or 50. The lower the pKa of a Bronsted acid, the more easily it gives up its proton. " - Pka leitung

WebMar 13, 2024 · Working with such numbers is inconvenient, so to makes things easier, chemists have defined the pKa number as: pKa = -log Ka. According to this definition, the pKa value for hydrochloric acid is -log 10 7 = -7, while the pKa for ascorbic acid is -log (1.6 x 10 -12) = 11.80. As is evident, the smaller the pKa number, the stronger the acid. WebIn simple terms, pKa is a number that shows how weak or strong an acid is. A strong acid will have a pKa of less than zero. More precisely – pKa is the negative log base ten of the Ka value (acid dissociation constant). It measures the strength of an acid — how tightly a proton is held by a Bronsted acid.
