Given: A certain weak acid,HA with a Ka value of 5.61 •10-6 is tutorage's with NaOH.
part A: a solution is made by titration 7.00mmol of HA and 3.00 mmol of the strong base. What is the resulting pH?
Part B: more strong base is added until the equivalence point is reached. What is the pH of this addition at the equivalence point if the total volume is 34mL?

Transcribed Image Text:A titration involves adding a reactant of known
quantity to a solution of an another reactant while
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
HA(aq) + OH(aq)→A¯(aq) + H₂O(1)
