Review Acid Base Equilbrium & Titrations? Bozeman Sci?
An analytical procedure used to determine the concentration of a sample by reacting it with a standard solution
Solution of known concentration used in titration. Substance being analyzed. Enough titrant added stoichiometrically react exactly with the analyte to neutralize it. The indicator changes color so you can tell the equivalance point has been reached.
Standardization of a NaOH solution using Potassium Acid Phthalate (KHP). An aqueous solution of NaOH was standarized by titrating it against a sample of KHP. The chemical formula is HKC 8 H 4 O 4.
Initial reading taken from the buret containing NaOH was 0.52mL and the final volume was 32.86mL. What is the molarity of the NaOH solution?
The reaction equation is: HKC 8 H 4 O 4 + NaOH NaKC 8 H 4 O 4 + H 2 O H + + KC 8 H 4 O 4 - + Na + + OH - Na + + KC 8 H 4 O 4 - + H 2 O H + + OH - H 2 O
