On the other hand, broken items nevertheless demand thorough cleanup, as mercury is often difficult to gather and it is easy to accidentally create a much larger exposure challenge.[65] If obtainable, powdered sulfur might be placed on the spill, to be able to create a solid compound that may be much more effortlessly eliminated from surfaces than liquid mercury.[sixty six]
Mercury(II) is the most common oxidation condition and is also the most crucial a person in character too.
