When 90.0mL of 0.10M Fe3 plus 3 is added to 10.0 mL of SCN minus 1, you get an equilibrium molar concentration of FeNCS plus 2. This is determined from a calibration curve of 1.0x10-6 mol/L.
b. Fe3 plus ions
To separate Fe3+ ions, one can use a reagent like ammonia (NH3) which forms a complex with Fe3+ ions called iron(III) hydroxide. This complex precipitates out of the solution, allowing for the separation of Fe3+ ions from other components in the mixture.
When Fe3+ and HCO3- combine, iron(III) bicarbonate or iron(III) hydrogen carbonate is formed. This compound is soluble in water and can undergo reactions that release carbon dioxide gas.
The answer is 3. Fe -> Fe3+ + 3e
Ferric = Iron(III) = Fe3+
FeCl3

Iron (III) ions form a deep-coloured complex with a maximum absorption at about 525nm; this complex is used as the basis for the photometric titration of iron(III) ion with standard EDTA solution.
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.
Zn(s) → Zn2+(aq) + 2e- and Fe3+(aq) + e- → Fe2+(aq)
Potassium thiocyanate can be used to confirm the oxidation of Fe2+ ions to Fe3+ ions by forming a blood-red complex with Fe3+, known as iron(III) thiocyanate. Upon the addition of potassium thiocyanate, if a blood-red color formation is observed, it indicates the presence of Fe3+ ions, confirming the oxidation of Fe2+ ions.
it should lose 3 electrons

The answer is 3. Fe -> Fe3+ + 3e
The reaction of FeSO4 (iron(II) sulfate) with K3PO4 (potassium phosphate) results in the formation of Fe3(PO4)2 (iron(II) phosphate) and K2SO4 (potassium sulfate).
