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. WebThe Henderson–Hasselbalch equation shows the correlation of the pK a and pH of the buffer solution.. The pK a of a given acid, or the conjugate acid of the base, is constant and therefore, the only variable in the equation is the logarithm term which depends on the acid-base pair concentrations..

WebNov 11, 2024 · pKa Definition. pK a is the negative base-10 logarithm of the acid dissociation constant (K a) of a solution. pKa = -log 10 K a. The lower the pKa value, the stronger the acid. For example, the pKa of acetic acid is 4.8, while the pKa of lactic acid is 3.8. Using the pKa values, one can see lactic acid is a stronger acid than acetic acid. WebNext, we can calculate the concentration of H + ions in the solution using the dissociation constant (Ka) for acetic acid: Ka = [H +][CH 3 COO-] / [CH 3 COOH] Since we know the pKa of acetic acid is 4.76, we can use the relationship: pKa = -log(Ka) to find the value of Ka: Ka = 10 (-pKa) = 1.75 x 10 (-5)
