Magnesio y Agua Reacciones Químicas

Magnesium reacts very slowly with cold water. This reaction accelerates with hot water. If I add copper sulfate (II) (CuSO4), the reaction also goes faster, even in cold water. This is because magnesium develops a thin layer of magnesium oxide (MgO) on its surface that protects it from the reactions with the external medium (passivation). Copper sulfate helps remove that layer so that the magnesium is in direct contact with water and reacts. So the copper sulfate acts as a catalyst. • Mg(s) + 2H2O (l) → Mg(OH)2 (s) + H2 (g) • Magnesium also reacts with water steam, but in a different way: • Mg(s) + H2O (g) → MgO (s) + H2O (g) • https://en.wikipedia.org/wiki/Magnesium • https://en.wikipedia.org/wiki/Passiva...) • Patreon ► / cienciabit • Susbcribe ► https://www.youtube.com/subscription_... • Do you want to contribute subtitles? ► http://www.youtube.com/timedtext_cs_p... • Cienciabit ► http://www.cienciabit.com • Cherry Blossom - Wonders by Kevin MacLeod is licensed under a Creative Commons Attribution license (https://creativecommons.org/licenses/...) • Source: http://incompetech.com/music/royalty-... • Artist: http://incompetech.com/
