The FeCl2 content test for a pickling line measures the concentration of ferrous chloride (FeCl2) in the pickling solution, which is used to remove oxide layers from metal surfaces. This test is important for ensuring optimal pickling efficiency, as the concentration of FeCl2 affects the solution's acidity and reactivity. Regular monitoring helps maintain the desired chemical balance, preventing issues like excessive corrosion or inadequate cleaning of the metal surfaces. Proper FeCl2 levels also contribute to the overall effectiveness and safety of the pickling process.
Because it's a test for phenols or enols
3 mole FeCl2 will react with 6 mole NaOH (stoechiometric mole ratio: 1 FeCl2 to 2 NaOH), so 3 mole FeCl2 (= 6 added -3 used) will be left over.

To ensure the content validity of a test, you need to ensure that you are covering all of the factors that the test seeks to analyze. If your test does not factor in the importance of a particular facet of the issue, your test will lack content validity.

The control test is the line that shows you the test is functioning properly. That line usually appears before your result line will show up.
