A student peforms a titration, titrating 25.00 mL of a weak monoprotic acid, HA, with a 1.28 M solution of NaOH. They collect data, plot a titration curve and determine the values given in the below table. Half-way Point Equivalence point How many moles of NaOH have been added at the equivalence point? mol What is the total volume of the solution at the equivalence point? mL ml NaOH added PH 18.41 3.23 36.82 8.41 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 K₂ of the weak acid (this is the hard way of estimating K₂) Use the pH at the half-way point to estimate K₂ of the weak acid (this is the easier way)
