With 33% people deficient in Iron, simple ways to increase absorption and intake of iron

SOLVED: In a dilute nitric acid solution, Fe3 reacts with thiocyanate ion (SCN-) to form a dark red complex: [Fe(H2O)6]3 SCN- ⇌ H2O [Fe(H2O)5NCS]2 . The equilibrium concentration of [Fe(H2O)5NCS]2 may be determined by how dark the colored solution is (measured by a spectrometer). In one such experiment, 1.0 mL of 0.20 M Fe(NO3)3 was mixed with 1.0 mL of 7.7 × 10-3 M KSCN and 8.0 mL of dilute HNO3. The color of the solution quantitatively indicated that the [Fe(H2O)5NCS]2 concentration

Fe3O4 HNO3 (loãng) → Fe(NO3)3 NO ↑ H2O | Fe3O4 HNO3 ra NO.
