1) The acid dissociation constats for phosphoric acid (H3PO4) ARE
K1=7.11x10^-3 K2=6.32x10^-8 K3=4.5x10^-3
a) what will be the concentration of the undissoaciated (H3PO4) form of phosphoric acid if you prepare 1.0 L of a solution that has 0.20 moles of H3PO4 at pH 8.0?
b) Calculate the hydronium ion concentration of 1.00x10^-3 M Na2HP04
2) A silver nitrate solution contains 14.77 g of AgNO3 in 1.0 L. What volume of the solution will be needed to react with 0.2631g of Nacl? (Ag=107.7 g, N=14, Na=23, Cl=35.5)
