WebCalculate the final volume of the solution. Use a RICE table to calculate the final concentration of the buffer acid and conjugate base. 9. Use the Henderson-Hasselbalch equation to calculate the pH of buffer solution A after the reaction with 15.0 mL of 0.100 M HCl (aq). Compare the pH to the experimentally measured pH (compute percent error). WebThis form of the ionization or dissociation constant expression is called the Henderson-Hasselbalch equation. This equation is very useful in calculating the pH of a solution containing a weak acid and its conjugate base (or salt). A comparable equation is obtained for a buffer solution consisting of a mixture of a weak base and its salt, namely:
