1. An aqueous solution of weak base B of unknown concentration is tritrated with aknown concentration of strong acid, HA.
(a) Write the balanced chemical equation for this acid-base reaction, identifying theconjugate acid/base pairs.
(b) If the base-dissociation constant of B is 1 × 10−3, what is the pH at the midpointof the buffer region? What are the chemical components of the buffer?
(c) Write the balanced chemical equation for the weak acid dissociation in wateroccurring at the equivalence point.5
(d) At the equivalence point, 500mL of 0.2 M HA(aq) was added to 500mL of theoriginal B(aq)solution. What is the pH at the equivalence point?
(e) Sketch the titration curve, labeling all axes, the buffer region, and equivalencepoint, along with corresponding pH values.
