Web31 jan. 2024 · All acids of the generic formula HA have pKa. HA − ⇀ ↽ − H + + A −. The equilibrium constant for this simplified reaction can be written as. Keq = [H +][A −] HA Ka = [HA]Keq = [H +][A −] pKa = − logKa. The pK a becomes a simple measure of the strength of an acid. The stronger the acid, the larger the K a and the smaller the pK a. WebWeak acid: AH + H 2 O ↔ A - (aq) + H 3 O + (aq) Weak base: BOH + H 2 O ↔ B + (aq) + OH - (aq) or B + H 2 O ↔ BH + (aq) + OH - (aq) Examples of weak acids and bases are given in the table below. Stronger acids have a larger acid dissociation constant (Ka) and a smaller logarithmic constant (pKa = −log Ka) than weaker acids.

From Eq. (3.2) it can be seen that, since Ka is a simple ratio, the higher the numerical value of Ka the stronger will be the acid. As stated in Chapter 1, however, the … the orthodox way book pdf
