Webb16 mars 2024 · The pH to H+ formula that represents this relation is: \small \rm {pH = -\log ( [H^+])} pH = −log( [H+]) The solution is acidic if its pH is less than 7. If the pH is higher, … WebbUse the Henderson-Hasselbalch equation to determine the pH of a buffer solution made up of 0.15 M CH 3 COO – and 0.20 M CH 3 COOH. The pKa of acetic acid (CH 3 COOH) is 4.75. To solve this example problem, we want to start with the Henderson-Hasselbalch equation since we are looking at a buffer solution of a weak acid and conjugate base. Webb9 sep. 2024 · The pH of a buffer solution may be calculated as follows: p H = p K a + l o g n A n H A Where pK a = dissociation constant of the acid, nA = initial number of moles of salt in the buffer, and nHA = initial number of moles of acid in the buffer. diamond joinery
