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

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??
