Web7 de jul. de 2024 · Which has highest pKa value? The phenol and ethanol both are alcohols. Out of these phenols are more acidic than phenols. So, they will be least acidic and thus will have the highest pKa value. So, the correct answer is “Option D”. Which one has higher pKa value? A pKa may be a small, negative number, such as -3 or -5. 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.

WebSince the K a is a mathematical expression for the state of equilibrium, it is quite easy to interpret. If the K a value is small, we don’t have much of our products. No products … WebSo let's go ahead and look at all the possible scenarios for these three things. 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.
