Iron(III) Nitrate and Its Properties

The video explores whether iron III nitrate (Fe(NO3)3) is acidic, basic, or neutral when dissolved in water. It examines the neutralization reaction that forms iron III nitrate, involving iron III hydroxide and nitric acid. The video uses a table to determine the strengths of these substances, identifying iron III hydroxide as a weak base and nitric acid as a strong acid. According to the rules, the resulting solution is acidic, with a pH less than seven. Therefore, iron III nitrate dissolved in water results in an acidic solution.
