Question

MNOH+I+H
MNO₂ + Iz 4140 balese​

Answer 1

Answer:

Manganese(II) hydroxide precipitates as a solid when an alkali metal hydroxide is added to an aqueous solution of Mn2+ salt:[2]

Mn2+ + 2 NaOH → Mn(OH)2 + 2 Na+

Manganese(II) hydroxide oxidizes readily in air, as indicated by darkening of samples.

The compound adopts the brucite structure, as do several other metal dihydroxides.
