Green death

Green death is a solution used to test the resistance to corrosion of metals. It typically consists of 11.5-11.9 wt% sulfuric acid, 1.2-1.3 wt% hydrochloric acid, 1 wt% iron(III) chloride and 1 wt% copper(II) chloride boiling at ~103 °C.[1] The solution may also be used to define the critical pitting temperature (CPT) or the critical crevice corrosion temperature (CCT) of an alloy.

For the episode of Doctor Who, see The Green Death.
