In a laboratory experiment, a student is conducting a titration. In this titration, a 0.250 M solution of Sodium Hydroxide (NaOH) is added to 30.0 mL of an HCl solution with an unknown concentration. After adding the sodium hydroxide, the student determined that 15.0 mL of NaOH was needed to reach the equivalence point. Based on this information, what was the original concentration of the HCl solution? (Please provide your answer to 3 decimal places.)
For their first trial, a student pipettes 5.00 mL of a vinegar solution into an Erlenmeyer flask. The student titrates the vinegar with standardized NaOH with a molarity of 0.437 M. The volume of titrant used was recorded in the table above. Calculate the molarity of the vinegar solution for this trial. Enter a number without units.
A chemistry student needs to standardize a fresh solution of sodium hydroxide. He carefully weighs out 30. mg of oxalic acid (H,C,0,), a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250. mL of distilled water. The student then titrates the oxalic acid solution with his sodium hydroxide solution. When the titration reaches the equivalence point, the student finds he has used 62.3 mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Round your answer to 2 significant digits. x10
