Green death
open-in-new
<p>Green death is a solution used to test the resistance of metals and alloys to <a href="/facts/Corrosion/lIC7H4we">corrosion</a>. It consists of a mixture of <a href="/facts/Sulfuric_acid/Wom6fymJ">sulfuric acid</a>, <a href="/facts/HCl/7Wzkhomd">hydrochloric acid</a>, <a href="/facts/FeCl3/a51pulq1">iron(III) chloride</a> and <a href="/facts/Copper(II)_chloride/saTjsWXT">copper(II) chloride</a> and its <a href="/facts/Boiling_point/E2BK9QoS">boiling point</a> is at approximately 103 <a href="/facts/Celsius/okAEu1CA">°C</a>. Its typical <a href="/facts/Chemical_composition/vjo4uMQ0">chemical composition</a> is given in the table hereafter: </p> Chemical composition of the green death solution<table><tbody><tr><th>Reagent</th><th>Formula (—)</th><th>Usually (wt. %)</th><th>Min (wt. %)</th><th>Max (wt. %)</th></tr><tr><td><a href="/facts/Sulfuric_acid/Wom6fymJ">Sulfuric acid</a></td><td>H2SO4</td><td>11.9</td><td>11.5</td><td>11.9</td></tr><tr><td><a href="/facts/Hydrochloric_acid/HqItJlUT">Hydrochloric acid</a></td><td>HCl</td><td>1.3</td><td>1.2</td><td>1.3</td></tr><tr><td><a href="/facts/FeCl3/a51pulq1">Iron(III) chloride</a></td><td>FeCl3</td><td>1.0</td><td>1.0</td><td>1.0</td></tr><tr><td><a href="/facts/Copper(II)_chloride/saTjsWXT">Copper(II) chloride</a></td><td>CuCl2</td><td>1.0</td><td>1.0</td><td>1.0</td></tr></tbody></table>
