0.9 M NaOH is load into a buret - initial reading is 2.6 mL 2) 100 mL of HCl is placed under the buret. 3) 2 drops of phenolphthalein is added to the acid. 4) The base is slowly added to the acid until it turns pink. - final reading from the buret is 23.6 mL. WHAT IS THE MOLARITY OF THE ACID?

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.
