Review Acid Base Equilbrium & Titrations?

Bozeman Sci?

TITRATION:An analytical procedure used to determine the concentration of a sample by reacting it with a standard solution

ANALYTE:

Solution of known concentration used in titration.

TITRANT:

Substance being analyzed.EQUIVALANCE POINT:

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.

ENDPOINT:

Standardization of a NaOH solution using Potassium Acid Phthalate (KHP).

STANDARDIZATION CALCULATION:

An aqueous solution of NaOH was standarized by titrating it against a sample of KHP. The chemical formula is HKC8H4O4.

Initial reading taken from the buret containing NaOH was 0.52mL and the final volume was 32.86mL.

STANDARDIZATION CALCULATION:

What is the molarity of the NaOH solution?

The reaction equation is:

HKC8H4O4 + NaOH NaKC8H4O4 + H2O

H+ + KC8H4O4 -+ Na+ + OH- Na+ +

KC8H4O4 - + H2O

H+ + OH- H2O
