Lead acetate paper ascertains the presence of hydrogen sulfide Hydrogen sulphide form while processing raw oil low concentrations can be toxic hence the requirement to check at certain points of the process, can also be used to determine levels of sulphide in drinking water, well water or groundwater Sulphide containing solutions turn the paper from white to brown-black Thiols, thioketones or mercaptans do not provide a response to this paper.
