WebThe organic acids are weak in the sense that this ionisation is very incomplete. At any one time, most of the acid will be present in the solution as un-ionised molecules. For example, in the case of dilute ethanoic acid, the solution contains about 99% of ethanoic acid molecules - at any instant, only about 1% have actually ionised. WebWhat is the pKa of OH-? The pKa of water is 14 (at 25 C). It is only in some organic textbooks and a few general chemistry texts that the pKa is given as 15.7. The 15.7 … WebMar 16, 2024 · The pH scale (pH) is a numeric scale used to define how acidic or basic an aqueous solution is. It commonly ranges between 0 and 14 but can go beyond these values if sufficiently acidic/basic. The pH value is logarithmically and is inversely related to the concentration of hydrogen ions in a solution. tegamini instagram
