<span>The equation that describes the problem is Fe(NO3)3(aq) + 3NaOH(aq) ---> Fe(OH)3(s) + 3 NaNO3(aq)
The Net ionic equation is written as follows:
Fe^3(aq) + 3NO3-(aq) + 3Na+(aq) + 3OH-(aq) ---> Fe(OH)3(s) + 3Na+(aq) + 3NO^3-(aq)</span>
The answer would be A: The solution must result in a cure for skin cancer. And B: The solution must not cause harm to living organisms.
