Stu dent has finished his titration, and he comes to you for with the calculations. he tells you that 20.00 ml of unknown concentration hbr(aq) required 18.45 ml of 0.3500 m naoh(aq) to neutralize it, to the point where thymol blue indicator changed from pale yellow to very pale blue. calculate the concentration (molarity) of stu's hbr(aq) sample. kemmi major also does a titration. she measures 25.00 ml of unknown concentration h_2so_4(aq) and titrates it with 0.1000 m naoh(aq). when she has added 42.18 ml of the base, her phenolphthalein indicator turns light pink. what is the concentration (molarity) of kemmi's h_2so_4(aq) sample?
