Need help with both part A and part B. Thank you!

A certain weak acid, HA, with a Ka value of 5.61 x 10-6, is titrated with NaOH. A titration involves adding a reactant of known quantity to a solution of an another reactant while Part A monitoring the equilibrium concentrations. This allows one to determine the concentration of the second reactant. The equation for the reaction of a generic weak acid HA with a strong base is A solution is made by titrating 9.00 mmol (millimoles) of HA and 3.00 mmol of the strong base. What is the resulting PH? HA(aq) + OH-(aq)-A-(aq) + H2O(1) Express the pH numerically to two decimal places. View Available Hint(s) AEQ ? PH = Submit Part B 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 56.0 mL ? Express the pH numerically to two decimal places. View Available Hint(s) AE
