WebAug 15, 2024 · MnO 2 is generally insoluble in acids, but does react with hot concentrated hydrochloric acid to release chlorine gas. In acid solution, H 2O 2 becomes a reducing agent, and the MnO 2 will dissolve: MnO 2(s) + H 2O 2(aq) + 2H + (aq) Mn2 + (aq) + O … \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} … WebManganese II ions (Mn2+) are also responsible for red and pink body color in many gems such as Rhodochrosite (mostly translucent to opaque), which at times is even more magnetic than Spessartine Garnet. Manganese III (Mn3+) ions create color in much lower concentrations than Mn2+, resulting in weakly magnetic or diamagnetic gems.
