What is the pKa Calculator & How does it work?
The pKa value is a measure of the acidity or basicity of an aqueous solution. It is defined as the negative logarithm of the acid dissociation constant (Ka) of a weak acid in water.
The formula to calculate pKa is:
\[ \text{pKa} = -\log_{10}(K_a) \]
Ka = acid dissociation constant
Understanding pKa is crucial in chemistry, particularly in biochemistry and pharmacology, as it helps determine the protonation state of molecules under different pH conditions.
