Frequent Questions

What form of chromium is typical in a water sample containing chromium?

The form of chromium found in a typical water sample is dependent upon a number of factors.  Chromium-III is more likely to be predominant in waters that are highly reductive (such as those that contain metals like iron or magnesium) or that are low in pH.  Chromium-VI is more likely to be found in waters that contain an oxidant (such as chlorine) or that have a higher pH.
