D) 3.23 - fairly strong weak acid
E) cannot be determined from the information given
pKa
A quantitative measurement that describes the acidity of a substance, specifically the negative log of the acid dissociation constant (Ka).
Acid Strength
A measure of the propensity of a compound to donate a proton (H+) in an aqueous solution, often quantified by the acid dissociation constant (Ka).
Formic Acid
The simplest carboxylic acid with the chemical formula HCOOH, known for its role in ant stings.
