Objective:

Visually determine the molar concentration of a dichromate ion in an unknown solution of Cr2O7 using color bracketing.

Background:

Many ions impart a color to the aqueous solutions in which they are dissolved. The intensity of the and disadvantage phone color is directly proportional to basketball process, the concentration of the and disadvantage phone ion. When dissolved in water, the dichromate ion imparts a faint yellow color to the solution. The concentration may be determined by visual color comparison to a set of prepared standard solutions. Filtering solutions would be necessary if any turbidity was present, to eliminate interference. The concentration of the dichromate ion in the solution can be determined stoichiometrically.

Materials:

Unknown, dichromate solution

Standard stock solution, 0.100 M Cr2O7

Volumetric pipets, 5 ml and 10 ml

Graduated cylinders, 100 ml

Test Tubes, 50 ml

Parafilm

Test tube rack

Method:

Serial dilutions were made by diluting 5 ml of stock solution to a 100 ml final volume, then dilutions of 10:100, 82:100, 50:100 and 70:100 were made in pro life essay on abortion successive order of one another. The Advantage! Each dilution was transferred to a test tube, filling the page for an essay tube to a depth equal to the unknown to preserve constant path-length when viewing down through the tube against a white background. Of Mobile! All solutions were free of turbidity. Concentration of dichromate was determined by estimation of the color intensity as compared to two standards, one of higher and one of lower concentration. The final molar concentration was determined stoichiometrically from this estimated comparison.

Discussion:

The standard solutions used for comparisons are shown in the table below.

Dilution: Molar Concentration, Cr2O7:

Stock 0.100

D1 0.005

D2 0.0005

D3 0.00041

D4 0.000205

D5 0.0001435

Concentration of the unknown was estimated by both members of the lab group to be 0.0004 M. This was done by placing it between D3 and D4. The color of the pro life on abortion unknown was slightly less intense than the the advantage of mobile phone D3 standard.
