Stomach Acid Pka

Examples of weak acids include acetic acid (pKa = 4.7) and methanol (pKa = 15.5). our every day interactions with acid-base chemistry includes stomach acid.

If the pH is higher than the pKa, the site is mostly deprotonated, and if the pH is. Stomach, 1.0-3.5. The pKa is given for the both the conjugate acid and base.

The pKa of a weak acid was determined by measuring the pH of a solution containing. Calculate the volume of stomach acid with a pH of 1.0 that one of these.

This would make salicylate the weaker conjugate base, and therefore salicylic acid is the stronger acid. Apparently this effect is stronger than the effect of pi electron donation. Apparently this effect is stronger than the effect of pi electron donation.

Ascorbic acid is a weak acid (pKa= 4.2) [3], only slightly stronger than vinegar. When dissolved in water, vitamin C is sour but less so than citric acid found in lemons and limes. Can large quantities of a weak acid such as ascorbate cause problems in the body? The answer is, sometimes, in some situations. However, with some simple precautions they can be avoided.
