Webb19 feb. 2024 · So for a stronger acid (lower p K X a ), the negative charge must be more stabilized. When comparing C F X 3 C O O H (TFA) to C H X 3 C O O H (we'll use acetic acid to represent a "typical" carboxylic acid), TFA is stronger than acetic acid because its conjugate base can better stabilize the negative charge. WebbI dag · Strong acids have a high value for acid dissociation constant (Ka) and a low value for logarithmic constant (pKa). For example, the Ka and pKa value for HCl is 1.3 X 106 and – 6.3, respectively. Weak acids, on the other hand, only partially ionize in a solution. Their strength is estimated from dissociation capacity.
