1) 45.0 mL of 0.125 M benzoic acid C6H3COOH is titrated with 0.25 M NaOH. Ka of the acid is 6.46 x 10-5. Calculate the pH of the solutions at the following points of the
titration. Indicate whether the solution is buffer or not at these points.

What happens to the atomic radius when an elctron is lost

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 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 of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
