You are in the lab and run a titration with 0.50 M NaOH as the titrant (in the burette) and 50.0 mL of HCl (in the flask) with an unknown concentration. You proceed through the titration using bromothymol blue as the indicator. The color changes from yellow to blue after 27.7 mL of NaOH is added, telling you that the equivalence point has been reached. What is the concentration of the HCl solution in the flask?
Balanced equation: NaOH + HCl → H2O + NaCl

0.0007 M
0.14 M
You are in the lab and run a titration with 0.500 M LiOH as the titrant (in the burette) and 75.0 mL of H2SO4 (in the flask) with an unknown concentration. You proceed through the titration using bromothymol blue as the indicator. The color changes from yellow to blue after 24.5 mL of LiOH is added, telling you that the equivalence point has been reached. What is the concentration of the H2SO4 solution in the flask?
Balanced equation: 2LiOH + H2SO4 → 2H2O + Li2SO4
