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
