'''Peroxydisulfuric acid''' or '''Marshall's acid''', is a chemical compound, a strong oxoacid with the chemical formula '''H<sub>2</sub>S<sub>2</sub>O<sub>8</sub>'''. The free acid is not used in chemistry, but it's salts are more often encountered.<br />
<br />
==Properties==<br />
===Chemical===<br />
Peroxydisulfuric acid will react violently with many organic compounds.<br />
<br />
Hydrolysis of peroxydisulfuric acid produces [[hydrogen peroxide]] and [[sulfuric acid]]:<br />
<br />
: H<sub>2</sub>S<sub>2</sub>O<sub>8</sub> + 2 H<sub>2</sub>O → 2 H<sub>2</sub>SO<sub>4</sub> + H<sub>2</sub>O<sub>2</sub><br />
<br />
Partial hydrolysis of peroxydisulfuric acid produces [[peroxymonosulfuric acid]] and sulfuric acid.<br />
<br />
: H<sub>2</sub>S<sub>2</sub>O<sub>8</sub> + H<sub>2</sub>O → H<sub>2</sub>SO<sub>5</sub> + H<sub>2</sub>SO<sub>4</sub><br />
<br />
===Physical===<br />
Peroxydisulfuric acid is a hygroscopic colorless solid, that is soluble in water.<br />
<br />
==Availability==<br />
The pure acid is not sold, instead its salts are more readily available.<br />
<br />
==Preparation==<br />
Can be prepared by adding concentrate [[sulfuric acid]] to [[sodium persulfate]].<br />
<br />
The acid can also be prepared by the reaction of [[chlorosulfuric acid]] with [[hydrogen peroxide]].<ref>https://onlinelibrary.wiley.com/doi/abs/10.1002/14356007.a19_177.pub2</ref><br />
<br />
: 2 ClSO<sub>3</sub>H + H<sub>2</sub>O<sub>2</sub> → H<sub>2</sub>S<sub>2</sub>O<sub>8</sub> + 2 HCl<br />
<br />
==Projects==<br />
*Make persulfate salts<br />
<br />
==Handling==<br />
===Safety===<br />
Peroxydisulfuric acid is highly corrosive and may explode in contact with organic substances.<br />
<br />
===Storage===<br />
Peroxydisulfuric acid is not very stable, but at least one source claims it can be kept relative stable at low temperatures, for up to 8 weeks.<ref>D'Ans, J.; Zeitschrift fuer Elektrochemie; vol. 17; (1911); p. 849 - 851</ref>. Aqueous solutions of this acid are more stable at 0-17 °C.<ref>Elbs, K.; Schoenherr, O.; Zeitschrift fuer Elektrochemie; vol. 1; (1894); p. 468 - 472,</ref><br />
<br />
Peroxoacids should not be stored, as they will react violently with anything organic (dust, particulates, hair strands, etc.).<br />
<br />
===Disposal===<br />
Should be dissolved in water and neutralized with a reducing agent and a base.<br />
