4 2 Points The Titration Curve Below Depicts The Neutralization Of A Polyprotic Base Ppb With 0 15 M Hydrochloric A 1 (1.12 MiB) Viewed 78 times

4. (2 points) The titration curve below depicts the neutralization of a polyprotic base, PPB, with 0.15 M hydrochloric acid. Polyprotic bases are like polyprotic acids, in that they can accept more than 1 hydrogen. a. If it requires 5.5 mL to reach the 1st equivalence point, how many mL of mol HA- = 0 hydrochloric acid would be needed to completely neutralize the base? 0.1SM (0.055)= 0.00825 mol на mol HA-mol A = 0 at eg. por X -| на + b. At approximately what volume (mL) would pOH = pKb2 (Kb2 is the second protonation reaction)? ~2(eg₁) = 2 (5.5) = 4²
