A certain weak acid, HA, with a Ka value of 5.61×10−6, is titrated with NaOH.

Part A

A solution is made by titrating 9.00 mmol (millimoles) of HA and 1.00 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 solution at the equivalence point if the total volume is 50.0 mL ?

A certain weak acid, HA, with a Ka value of 5.61×10−6, is titrated with NaOH.

A solution is made by mixing 9.00 mmol (millimoles) of HA and 3.00 mmol of the strong base. This resulted in a pH of 4.95.

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 77.0 mL ?

Express the pH numerically to two decimal places.

Please help!! Please show steps if possible. THANK YOU!!

± Titration of Weak Acid with Strong Base 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(l) A certain weak acid, HA, with a Ka value of 5.61×10−6, is titrated with NaOH.
