To find the van't Hoff factor (i) for the weak acid HA, we can follow these steps:Step 1: Determine the dissociation constant (Ka) Given that \( pKa = 4 \), we can calculate \( Ka \) using the formula: \( Ka = 10^{-pKa} = 10^{-
The pKa of an acid is a constant associated with how much the acid ionizes in solution. pKa is a combination of the p in pH, which stands for power of hydrogen, and the dissociation constant for acids, represented by Ka. Since strong acids, by definition, ionize completely, pKa is more...

How do you get pKa from Ka? or pH from concentration of H?What is the concentration of the hydrogen ion, if the pH of a solution is 7? ( Answer in moles/liter)If the pH of a solution of HCl is 4, what is its ...

This pKa calculator helps you find the pKa from pH with the Henderson-Hasselbalch equation or with acid dissociation constant (Ka) values.
