Bоnus Questiоn (5 pоints extrа credit) Consider а titrаtion of a 25.0 mL sample of 0.110 M of the weak acid HA (where A is the the anion) with 0.125 M NaOH. The Ka for HA is 1.8x10-5. HA ⇌ H+ + A- or HA + H2O ⇌ H3O+ + A- At the equivalence point for this titration what will be the pH? This is the same question as earlier but this time input the actual pH value. Input the pH with two decimal places.
