Question

"Which equation correctly represents the third ionization of iron?

a. Fe(s) → Fe^3+(g) + 3e^-
Fe^2+(g) → Fe^3+(g) + e^-
Fe(g) + 3e- → Fe3-(g) ,
Fe(s) → Fe3+(g) + e- ,
Fe3+(g) + 3e- → Fe(s)"

Answer 1

The equation that correctly represents the third ionization of iron is Fe²+(g) → Fe³+(g) + e-. In this reaction, one electron is added to a singly ionized iron ion (Fe²+) to form a doubly ionized iron ion (Fe³+).

Step-by-step explanation:

The equation that correctly represents the third ionization of iron is:

Fe²+(g) → Fe³+(g) + e-

In this reaction, one electron is added to a singly ionized iron ion (Fe²+) to form a doubly ionized iron ion (Fe³+).
