1. Calculate the equivalence point volume for titration of 45.8 mL of 0.12 M HClO4 with a sample of 0.35 M NaOH. 2. The drop-counter is misaligned with the buret, causing it to miss counting every one out of five drops of base added to the HCl. This error means the calculated molarity of the HCl solution will be ___________ its actual concentration. --> the same as, lower, or higher

Draw the titration curve for the titration of 20 mL of a 0.12 M solution of glutamate (carboxylic acid pKa = 2.19, amino pKa = 9.67, you need to know the pKa for the R group) with 0.10 M sodium hydroxide. Clearly label the axes of your graph (pH vs mL of NaOH added.) Be sure to include pH values and volumes for the following: Start of the titration (no sodium hydroxide added), the pH at the volume that is...
