13. Sketch a titration curve for the titration of a monoprotic weak acid HA with a strong base. The titration reaction (neutralization) is: HA + OH + H2O+ A On the curve, clearly label the points that correspond to: i. the equivalence point ii. the region with maximum buffering iii. pH = pka iv. pH depends only on [HA] v. pH depends only on [A-] vi. pH depends only on amount of strong base added.

During the titration the following reaction occurs HA + NaOH = NaA+H2O What is the concentration of A (the conjugate base of the weak acid) at the equivalence point? M Use [A] and the pH at the equivalence point to estimate Ko of the weak acid (this is the hard way of estimating K.) Use the pH at the half-way point to estimate of the weak acid (this is the easier way) Your grade will be shown after clicking 'Grade'...
