In my answer, I stated that manganese is said to not react with water under normal conditions although some sources say it reacts with water to liberate hydrogen gas. Does it implies that it reacts with water at harsh conditions?

WebElements and ChemLibreTexts states that "Manganese does not react with water under normal conditions" whereas Lenntech says "it reacts with water (it rusts like iron) and dissolves in dilute acids." What does rusting here mean? Does manganese rust like iron?

In some sources and Concise Inorganic Chemistry by J.D.LEE states "At room temperature very slowly reacts with water"

$$\ce{Mn + 2H2O -> Mn(OH)2 + H2}$$

and some says that it reacts and oxidizes all the way to permanganate. The results are inconsistent and sometimes contradictory.

Question: Does manganese reacts with water? If so, in what condition (standard or harsh)?

    $\begingroup$ Many metals react with steam, which may be considered a reaction with water at harsh conditions. Manganese is among them. $\endgroup$ Jun 18 at 11:41
