WebThe Henderson-Hasselbalch equation takes as inputs the concentrations of the acid and base to determine the pH of the solution (along with the pKa). In this problem we don’t have that; instead we are mixing a weak acid, acetic acid, with a strong base, sodium hydroxide. WebSo the concentration was 0.200 molar, so for our concentration of acetic acid, our concentration was equal to 0.200 molar, and that's equal to moles over liters. We started with 50 milliliters, which is 0.500 liters. So we multiply 0.200 by 0.0500, and we get 0.0100 moles of acetic acid.
