2: Suppose a student a titration of an unknown Experiment conducted solution of the weak acid HNO2 with .0.265 M NaOH. First, the student diluted 15.0 mL1 of the HNO2 solution with 85.0 mL of water in an Erlenmeyer flask and added 2 drops of the indicator, phenolphthalein. Then, 0.265 M NaOH was titrated into the diluted HNO2 solution until the color of the solution changed to pink and the end point of the titration was reached. the end point, 9.00 mL of 0.265 NaOH was added to the HNO2 solution. Calculate the concentration of the HNO2 solution. 2: Suppose a student a titration of an unknown Experiment conducted solution of the weak acid HNO2 with .0.265 M NaOH.
