WebVideo transcript. - Here we have a titration curve for the titration of 50 milliliters of 0.200 molar of acetic acid, and to our acetic solution we're adding some 0.0500 molar sodium hydroxide. So once again we're putting pH in the Y axis, and down here in the X axis is the milliliters of base that we are adding.

WebASK AN EXPERT. Science Chemistry Chlorous acid, HClO2, is a weak monoprotic acid with Ka = 1.1 × 10−2. Calculate the pH of a 0.869 M solution of this acid. Report your answer to TWO places past the decimal. Chlorous acid, HClO2, is a weak monoprotic acid with Ka = 1.1 × 10−2. WebCalculating the pH of a buffer solution requires the Henderson-Hasselbalch equation and knowledge of the concentrations (in molarity) of both the weak acid and its conjugate base. The second method directly introduces both the acid/base pair species and simply requires a calculation to determine the molarities of both after mixing.
