A certain weak acid, HA, with a Ka valueof 5.61?10?6, is titrated with NaOH.
Part A
A solution is made by titrating9.00mmol (millimoles) of HA and 3.00mmol of thestrong base. What is the resulting pH?
Express the pH numerically to two decimal places.
Part B
More strong base is added until the equivalence point isreached. What is the pH of this solution at the equivalence pointif the total volume is 74.0mL ?
Express the pH numerically to two decimal places.
