Free pKa calculator for chemical compounds. Enter any formula to find acid dissociation constants. Essential tool for buffer design, drug development, and acid-base chemistry research.
Enter a chemical formula to calculate its pKa value. The pKa value indicates the strength of an acid in solution.
The pKa value is a quantitative measure of the strength of an acid in solution. It is the negative base-10 logarithm of the acid dissociation constant (Ka) of a solution.
Enter a chemical formula in the input field above. The calculator will display the corresponding pKa value if the compound is in our database.
