Frequently Asked Questions on Chromium III Nitrate
Question 1: What is the molar mass of Chromium III nitrate?
Solution:
The formula of Chromium III Nitrate is Cr(NO3)3
= 51.9961 + (14.0067 + 15.9994×3)×3
= 238.0108 g/mol.
Question 2: Is Chromium (III) Nitrate soluble or insoluble?
Answer:
Chromium nitrate (Cr (NO3)3) is a crystalline chromium compound that is easily dissolved in water. Some of the synonyms for chromium nitrate are chromium trinitrate non-hydrate, chromium nitrate non-hydrate, chromium nitrate, and chromium nitrate non-hydrate.
Question 3: What is chromium nitrate used for?
Answer:
Chromium nitrate is a light green powder. It is used as a chrome catalyst manufacturing, printing, and corrosion inhibitor.
Question 4: What does III mean in Chromium (III) Nitrate?
Answer:
In this case, the name of the compound contains the Roman numeral (III). This means that the metal has an oxidation state of +3. In other words, cations carry a 3+ positive charge, chromium (III) cation.
Question 5: Why is nitric acid a powerful oxidizer?
Answer:
In the case of nitric acid (HNO3), nitrogen has the highest oxidation state of +5, so it is reduced to oxidize other molecules. Therefore, it acts as an oxidant.
Question 6: Why does nitric acid change the color of the precipitate?
Answer:
Pure nitric acid is colorless. Nitric acid is so unstable to heat that it decomposes. When they decompose, they form a reddish brown nitrogen dioxide gas. It turns yellow when dissolved in acid.
Question 7: What are the harmful effects of Chromium (III) nitrate?
Answer:
- Chromium nitrate can be affected when inhaled.
- Contact may irritate the skin and eyes or cause burns.
- Inhalation of chromium nitrate can irritate the nose, throat, and lungs and cause coughing, wheezing, and shortness of breath.
- Chromium nitrate can cause skin allergies.
Chromium III Nitrate Formula – Structure, Properties, Uses, Sample Questions
Chromium (Cr), a chemical element of Group 6 (VIb) of the Periodic Table, is a hard steel that is highly polished and used in alloys to increase strength and corrosion resistance-grey metal. Mainly used as electroplating, tanning, printing, dyeing, medicine, fuel, catalyst, oxidizer, match, and metal corrosion inhibitor. At the same time, metallic chromium has evolved into one of the most important electroplated metals. Nitrate is an inorganic compound consisting of one nitrogen atom (N) and three oxygen atoms (O). The chemical symbol for nitrate is NO3. Nitrate is usually not harmful unless it is reduced to nitrite (NO2).
Nitrate is used as a fertilizer in agriculture due to its high solubility and biodegradability. The main fertilizers are ammonium salt, sodium salt, potassium salt, calcium salt, and magnesium salt.
