Iron (III) Nitrate Formula
Question 1: What is the chemical formula of iron (III) nitrate?
Answer:
Iron (III) nitrate is also referred to as ferric nitrate or iron trinitrate, whose chemical (or) the molecular formula is Fe(NO3)3 (or) FeN3O9. It is an inorganic compound that appears as a violet crystalline solid. Nonahydrate is the most common hydrate form, with the chemical formula Fe(NO3)3. (H2O)9.
Question 2: How is iron (III) nitrate prepared?
Answer:
- Iron (III) nitrate can also be prepared by treating hematite (Fe2O3) with nitric acid.
Fe2O3 + 6HNO3 → 2Fe(NO3)3 + 3H2O
- The action of nitric acid on iron metal powder can produce iron(III) nitrate.
Fe + 4HNO3 → Fe(NO3)3 + NO + 2H2O
Question 3: What are the applications of iron (III) nitrate?
Answer:
As iron (III) nitrate has no large-scale applications, it acts as a catalyst in the production of sodium amide from a solution of sodium in ammonia. Jewelers and metalworkers etch silver and silver alloys with the help of iron (III) nitrate solutions. It is used as a mordant in dyeing, weighting silks, tanning, and inhibiting corrosion, and also as a reagent in analytical chemistry.
Question 4: Mention some properties of iron (III) nitrate.
Answer:
Iron (III) nitrate is also referred to as ferric nitrate or iron trinitrate, whose molecular formula is FeN3O9. It appears as a violet crystalline solid and is completely soluble in water, alcohol, and acetone, and is slightly soluble in cold concentrated nitric acid. Though it is non-flammable, it will increase the intensity of a fire if it comes in contact with combustible materials. Its melting point is 47.2 °C whereas its boiling point is 125 °C.
Question 5: Mention some hazards of iron (III) nitrate.
Answer:
The inhalation of ferric nitrate dust irritates the nose and throat. Ingestion of iron (III) Nitrate may irritate the mouth and stomach. Prolonged contact with it may irritate the skin and also irritate the eyes. Chronic exposure may affect the liver. It is a strong oxidant, and there is a possibility of a dangerous fire as it comes into contact with organic material. Toxic nitrogen oxides and nitric acid vapor may form in fires.
Question 6: What happens when iron (III) nitrate reacts with copper?
Answer:
Iron (III) nitrate reacts with copper to form copper(II) nitrate (Cu(NO3)2) and ferrous nitrate (Fe(NO3)2).
Cu + 2Fe(NO3)3 → Cu(NO3)2 + 2Fe(NO3)2
Iron III Nitrate Formula
Iron (III) nitrate is also referred to as ferric nitrate or iron trinitrate, whose chemical (or) the molecular formula is Fe(NO3)3 (or) FeN3O9. It is an inorganic compound that appears as a violet crystalline solid. Nonahydrate is the most common hydrate form, with the chemical formula Fe(NO3)3.(H2O)9. It is completely soluble in water, alcohol, and acetone, and is slightly soluble in cold concentrated nitric acid. It is a strong oxidant and a non-combustible chemical compound. Though it is non-flammable, it will increase the intensity of a fire if it comes in contact with combustible materials. The solutions of Ferric Nitrate are corrosive to most metals. It is used as a mordant in dyeing, weighting silks, tanning, and inhibiting corrosion, as well as a fertilizer and food additive.
