Question

Взаимодействует ли Mn2O7 с H2O? И почему, если Mn-металл 7б группы?

Answer 1

Ответ:

Mn2O7 + H2O → 2HMnO4

Реакция возможна. Взаимодействие кислотного оксида с водой, образуется марганцовая кислота.

Answer 2

Manganese(VII) oxide, also known as permanganic acid, Mn2O7, is a highly reactive and powerful oxidizing agent. When it comes into contact with water (H2O), it reacts vigorously. The reaction with water can be represented as follows:

Mn2O7 + H2O → 2 HMnO4

In this reaction, Mn2O7 reacts with water to form two molecules of permanganic acid (HMnO4).

The high reactivity of Mn2O7 can be attributed to the fact that it contains manganese in its highest oxidation state, +7. Manganese is a transition metal, and in its +7 oxidation state, it has lost seven electrons, making it highly unstable and prone to reacting with other substances, including water, to achieve a more stable configuration.

So, in summary, Mn2O7 does indeed react with H2O because of its highly oxidizing nature and the desire of the manganese atoms to achieve a more stable oxidation state by transferring electrons to other species like water.
