The scenes below depict the relative concentrations of h3po4, h2po4− , and hpo42− during a titration with aqueous naoh, but they are out of order. (phosphate groups are purple, hydrogens are blue, and na+ ions and water molecules are not shown.) (a) list the scenes in the correct order. first last (b) what is the ph in the correctly ordered second scene (ka1 = 7.2 × 10−3, ka2 = 6.3 × 10−8)? ph = (c) if it requires 28.00 ml of the naoh solution to reach this scene, how much more is needed to reach the last scene? ml naoh
