Ka value related to ph
WebIn chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted ) is a quantitative measure of the strength of an acid in … WebTo find the pKa of acetic acid, we take the negative log of the Ka value. So the negative log of 1.8 times 10 to the negative fifth is equal to 4.74. So we can go back to the Henderson-Hasselbalch equation and write that the pH is equal to the pKa, which we just calculated to be 4.74 plus the log of the concentration of the conjugate base.
