I came across a website that said it is possible for sodium hydroxide to react with manganese dioxide at temperatures near 0 degrees Celsius. The reaction goes: 2MnO2 + 3NaOH ⇄ MnO(OH) + Na3MnO4 + H2O [
Source: https://chemiday.com/en/reaction/3-1-0-7458 Is this actually a feasible reaction and if so how would one tilt the equilibrium to the right?
