A student titrated 50 mL of an H_2SO_4 solution with 0.2 M NaoH using a phenolphthalein indicator. The student found that it took 50 mL of NaoH to reach the equivalence point. Using the following equation: M_1V_1 = M_2V_2 the student was able to determine the concentration of the H_2SO_4 solution to also be 0.2 M. Is this the correct concentration of the unknown H_2SO_4, solution? If not, what did the student do incorrectly?
