Iron

Remove the 2 indicator sticks, pipette, vials and litmus paper from the large test tube
Cut the litmus paper into a few pieces - about 5 or 6 small pieces
In the empty large test-tube, add 2 ml. (maximum) of the solution to be tested
Check the pH solution to be tested in the large test-tube by dropping a piece of litmus paper in it
If the solution is too alkaline (the litms paper turns blue), add 2 drops of the colourless Reagent 2 from the vial with the yellow-cap with the help of the pipette into the solution in the large test-tube
Shake the large test-tube gently to mix the solutions. Check again by dropping another piece of litmus paper into the mixed solution in the large test tube
If the solution is still too alkaline, repeat steps (5) and (6). Repeat this procedure until the mixed solution in the large test-tube turns the litmus paper pink or red (acidic)
The solution is now ready for testing of Iron (FeII) and Iron (FeIII) ions

Conducting the test
Test 1 - Test for Iron (FeII):

Put the indicator stick into the mixed solution in the large test-tube for one (1) second. The reaction area of the indicator stick must be completely immersed in the solution in the large test-tube
Pull out the indicator stick and shake off any excess liquid
Wait 10 seconds and compare the colour of the indicator stick to the colour strip provided
Take note of the reading from the colour chart

Test 2 - Test for Iron (FeIII):

Add all the powder in the clear-cap vial (Reagent 1) to the solution to be tested in the large test-tube
Close the cap of the large test-tube and shake gently for a very short while
Put the second (unused) indicator stick into the mixed solution in the large test-tube for one (1) second. The surface of the indicator stick must be completely immersed in the solution in the large test-tube
Pull out the indicator stick and shake off any excess liquid
Wait 10-15 seconds and compare the colour of the indicator stick to the colour strip provided
Take note of the second reading from the colour chart
The concentration shown in this test indicates the total ions of Iron (FeII) and Iron (FeIII). In order to find out the concentration of Fe(III) ions, subtract the results obtain in Test 1

The numbers indicate parts per million.
