irvine! whaaaddup!

yup he's right.

I don't understand how I would have to find the pH at 0mL or at 5 mL added or at 10 mL added. are the equivalence points at 10mL, 20mL, 30 mL? and the k3 that you are referring to did you get that from the pK3?

so for 0mL added would it be k3 = [(HAsO4^-2)(OH^-)/(AsO4^-)] K3 = (x^2)/(0.1M of AsO4) pk3 = -log k3. then solve for x which would give you [OH^-] which you could use to find pOH and find pH by using pH + pOH = pKw??

thank you!! for 25 mL would i still be able to use the h-h equation since k1>10^-5?
