WEBApr 10, 2024 · The pKa of acetic acid is 4.745. Given the K a of 1.8 × 10 -5, pK a can be calculated as follows: pK a = -log 10 [K a] pK a = - (-4.745) = 4.745. This pKa calculator helps you find the pKa from pH with the Henderson-Hasselbalch equation or with acid dissociation constant (Ka) values.

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 a negative value 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.

WEBApr 28, 2021 · Because pKb = − logKb, Kb is 10 − 9.17 = 6.8 × 10 − 10. In this case, we are given Kb for a base (dimethylamine) and asked to calculate Ka and pKa for its conjugate acid, the dimethylammonium ion. Because the initial quantity given is Kb rather than pKb, we can use Equation 16.5.10: KaKb = Kw.
