<p>1. An aqueous solution of weak base B of unknownconcentration is tritrated with aknown concentration of strongacid, HA.</p>
<p>(a) Write the balanced chemical equation for thisacid-base reaction, identifying theconjugate acid/basepairs.</p>
<p>(b) If the base-dissociation constant of B is 1 ×10−3, what is the pH at the midpointof thebuffer region? What are the chemical components of thebuffer?</p>
<p>(c) Write the balanced chemical equation for the weak aciddissociation in wateroccurring at the equivalencepoint.5</p>
<p>(d) At the equivalence point, 500mL of 0.2 M HA(aq) wasadded to 500mL of theoriginal B(aq)solution. What is the pH at theequivalence point?</p>
<p>(e) Sketch the titration curve, labeling all axes, thebuffer region, and equivalencepoint, along withcorresponding pH values.</p>
