Question

M -->M+ + e-
What reactions does this equation represents ?

Answer 1

This equation represents oxidation reaction.

Or

This equation is also representation of ionization of atom.

Step-by-step explanation:

The oxidation is a chemical reaction where an atom loses electrons or gain oxygen or loses hydrogen.

Due to loss of electron or hydrogen or gain of oxygen there is an increase in its oxidation state.

i) it changes from negative to zero

ii) it changes from negative to positive

iii) it changes from more negative to less negative

iv) it changes from zero to positive

v) it changes from less positive to more positive.

In the given reaction the metal loses electron and gets oxidized.

We can also that the metal gets ionized.

Answer 2

The reaction that the equation M M + + e- represents is oxidation. M has lost an electron, and is the reducing agent in this equation.
