A 0.525 M solution of an unknown monoprotic acid has a pH = 2.24. What is the Ka of the acid? What is the percent ionization of the acid?
A certain weak acid, HA, with a Ka value of 5.61×10−6, is titrated with NaOH. A solution is made by titrating 46.19 mmol (millimoles) of HA and 2.24 mmol of the strong base. Then, more strong base is added until the equivalence point is reached. What is the pH of this solution at the equivalence point if the total volume is 85.1 mL ?
