A series of solutions containing NaOH, Na3AsO4, and Na2HAsO4, alone or in compatible combination, was titrated with 0.0954 M HCl. A 25.00 mL sample is titrated with 16.80 mL of standard HCl solution under phenolphthalein indicator. A second 25.00 mL aliquot requires 27.60 mL of the same titrant under the bromocresol green indicator.

Na3AsO4 is a salt of a weak base that can accept more than one proton. If 31 g of Na3AsO4 is dissolved in water to make 250 mL of solution, how many moles of sodium cations are in the solution? Answer in units of mol.

Sketch the titration curve for the following reaction: A 10.0 mL aliquot of 0.100M Na3AsO4 titrated with 0.100M HCl. pK1 = 2.25, pK2 = 6.77, pK3 = 11.60 --Can you also please write down all the steps on how you got to the answer (explain everything)? Thanks in advance!

moles of Na3AsO4 = moles of Ag3AsO4. Thus, moles of Ag3AsO4 = 7.99 x 10-5 moles. From moles and volume, molarity of Na3AsO4 can be calculated by using following equation. Molarity = moles/ volume in litre = 7.99 x 10-5 /0.010 L. Molarity of Na3AsO4 = 7.99 x 10-3 M. Sample 2, trial 1: calculation. Volume of AgNO3 = 50 - 48.35 ml = 1.65 ml
