Is ascorbic acid weak

Answer 1

The acid dissociation constant (Ka) is the measure of strength of an acid in solution. Symbolically, as HA is added to solution it breaks down into a proton (H+) and it's conjugate base (A-). The value of Ka is equal to products over reactants (aqueous only i.e. no solids or liquids) . Once you solve for Ka, you can solve for the pKa which is equal to -logKa. The pKa will determine if the acid is weak or strong. Strong acids are more willing to dissociate in water and have a pKa value of <-2. The pKa of ascorbic acid is only 4.2, and so it is a weak acid.

Answer 2

The pKa of ascorbic acid is only 4.2, so it is a weak acid. You can calculate the percent dissociation of a 0.1 M ascorbic acid solution using its Ka, and you will find that it is a small value.

Answer 3

Ascorbic acid, also known as vitamin C, is considered a weak acid compared to strong acids like hydrochloric acid. In solution, it can donate a hydrogen ion, making it slightly acidic. However, it is safe for consumption and plays a vital role in various biological processes in the body.

Answer 4

strong and weak
