Answer and Explanation:1 Acetic acid is a weak acid, its strength can therefore be expressed by its dissociation constant (Ka) or pKa value. pKa = -log(Ka) The pKa value of... Learn more about this topic: Autoionization & Dissociation Constant of Water ...
1. Acetic acid is widely distributed in nature. For example in fruit or vegetable oils, mainly in the form of esters; in the tissues of animals, excretions and blood are present in the form of free acids. Many microorganisms can convert different organisms into acetic acid by fermentation...
Acetic acid, with a pKavalue of 4.74, is approximately 15 times more acidic compared with acetone, with a pKavalue of 20. Why? ANSWERS OPTIONS A Acetic acid's conjugate base is more stabilized by electronegative oxygen than acetone's conjugate base....

Undissociated acetic acid (pKa 4.75) freely passes through cellular membranes, where it can then reach a new equilibrium with dissociated acetic acid at the intracellular pH. The net result is both uncoupling of the transmembrane pH gradient and an accumulation of acetate anion in the cytoplasm [...
For weak acids such as acetic acid, the Henderson-Hasselbalch equation can be applied. The Henderson-Hasselbalch equation is shown below: pH=pKa+log[A−][HA]Answer and Explanation: For acetic acid, we have pH=5.75 and pKa=4.75. Plugging them into t...
