My test solution turns yellow after I add the paint sample to test solution 1 bottle, but prior to adding test solution 2. Why is this happening?
The yellow tinge indicates chromates are present in your paint sample. This does NOT mean that lead is present as not all of the chromates used in paint contained lead. You must now finish the test by adding the 5 drops of solution 2 to the test bottle in order to determine if lead is indeed present.
