Titration problem?
A certain weak acid,HA with Ka =5.61*10^-6 is titrated with
NaOH.

1.A solution is made by mixing 8.00 millimoles of HA and 3.00 millimoles of base. What is the resulting pH?

2.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 48.0 mL?

n(NaOH) = n(OH-) = 0.003 mol
pOH = -lg 0.003
