Correct answer: B. Fe (NO3)3
- A. Fe2 (NO3)3
- B. Fe (NO3)3
- C. Fe3 (NO2)
- D. None of these
Explanation
In Fe(NO3)3, each nitrate ion has a -1 charge and three nitrates total -3, so iron must be Fe3+, or trivalent. The other written formulae do not correctly represent a normal neutral iron nitrate compound.
