Cadmium Nitrate Formula – Structure, Properties, Uses, Sample Questions

Cadmium is a chemical element with the symbol Cd. Its atomic number is 48. It is a soft, malleable, ductile, silvery-white divalent metal. Mining metal processing and battery production are the sources of cadmium exposure. It is found in meat, especially sweetmeats such as silver and kidney. it is used in batteries, alloys, electroplating, solar cells, and pigments.

Nitrogen is a chemical element with the symbol N . Its atomic number is 7. It belongs to15^th group of the periodic table. It is a colorless, odorless, and tasteless element. Nitrogen is the most abundant element in Earth’s atmosphere approximately 78% of the atmosphere is nitrogen. Nitrogen was discovered by Scottish scientist Daniel Rutherford in the year of 1772.

Oxygen is a chemical element with the symbol O. Its atomic number is 8. It is a member of the chalcogen group in the periodic table. It is an odorless, colorless, tasteless, diatomic gas consisting of 21 % of the atmosphere. It plays yah critical role in respiration. It is a reactive element found in water .in most rocks and minerals and in numerous organic compounds. The primary applications of oxygen include refining, melting, and manufacturing steel along with other metals.

Cadmium Nitrate

Cadmium Nitrate is a highly water-soluble crystalline inorganic compound with the formula Cd(NO₃)₂ .it is a white, odorless crystal that absorbs moisture from the air. It produces toxic cadmium oxide fumes on heating. It is used to give a reddish yellow luster to glass porcelain, in photographic emulsions and as a laboratory agent, It is a polyatomic iron of a single nitrogen atom ionically bound to three oxygen atoms. It is this source for cadmium compatible with nitrates and lower pH value. Cadmium nitrate is also referred to as carcinogenic.

Structure Of Cadmium Nitrate

The chemical structural formula of cadmium nitrate is Cd(NO₃)₂

In this compound, cadmium is a metal, and a nitrate ion is a group of nonmetals. To draw the Lewis structure for nitrate ion we have five valence electrons for nitrogen and 6 for oxygen totally we have 24 valence electrons. nitrogen is placed in the middle and surrounded by three oxygen atoms.

Preparation Of Cadmium Nitrate

• Cadmium nitrate is produced by dissolving cadmium metal or its oxide, hydroxide, or carbonate, in a nitric acid followed by crystallization

CdO + 2 HNO₃ —-> Cd(NO₃)₂ + H₂O

CdCO₃ + 2 HNO₃ —–> Cd(NO₃)₂ + CO₂ + H₂O    

Cd + 4 HNO₃ ——-> Cd(NO₃)₂ + 2 NO₂ + 2 H₂O

Physical Properties Of Cadmium Nitrate

• The molecular weight of cadmium nitrate is 236.42 g/mol
• Its density is 3.6 g/cm³
• Its melting point is 360^οC
• Its boiling point is 132^οC

Chemical Properties Of Cadmium Nitrate

• The chemical formula of cadmium nitrate is Cd(NO₃)₂
• Heating cadmium nitrate causes it to decompose to cadmium oxide and nitrogen dioxide

Cd(NO₃)₂ —–> CdO + 2 NO₂  + 1/2 O₂

• When cadmium nitrate reacts with sodium sulfide it undergoes a double displacement reaction.

Na₂S + Cd(NO₃)₂ ——–> 2 NaNO₃ + CdS

• An aqueous solution of cadmium nitrate is mixed with aqueous Potassium sulfide farming yellow of cadmium sulfide 

Cd(NO₃)₂ + K₂S  ——–> 2 KNO₃  + CdS

Use Of Cadmium Nitrate 

• Cadmium nitrate is used for coloring glass
• It is used as a flash powder in photography
• It is used for coloring porcelain
• It is used in nuclear reactors
• It is used in cadmium hydroxide production

Health hazards Of Cadmium Nitrate

• Cadmium Nitrate is a carcinogen
• Contact with cadmium nitrate can irritate the skin and eyes
• Inhaling it can irritate the nose, throat, and lungs
• It can cause nausea, vomiting, diarrhea, and abdominal pain
• It can cause both kidney and liver injuries.

Safety Measures for using Cadmium Nitrate

• Read all the instructions before using it
• It is a carcinogen so handle it with extreme caution
• To avoid contact with the eyes wear safety glasses
• Avoid contact with skin
• Wash hands thoroughly after handling it
• Avoid inhalation
• Store in tightly closed containers in cool, well-ventilated areas.

Sample Questions

Question 1: Is Cadmium a conductor of heat?

Answer:

Cadmium is a soft, malleable, bluish-white metal found in zinc ores. it is found naturally in the Earth’s crust and is a relatively rare metal. It is malleable, ductile, and can easily be cut with a knife. Due to its excellence as an electrical conductor. It is often used in electroplating and in batteries.

Question 2: What are the uses of oxygen?

Answer:

Oxygen is a chemical element with the symbol O. It has many uses. It is used by living beings in the respiration process. It is most commonly used in the production of steel, plastics, and textile.

Question 3: How to produce cadmium nitrate?

Answer:

Cadmium nitrate is an inorganic compound with the formula Cd(NO₃)₂. It is produced by dissolving cadmium metal or its oxide, hydroxide, or carbonate in nitric acid followed by crystallization.

CdO + 2 HNO₃ ——-> Cd(NO₃)₂ +H₂O

CdCO₃ + 2 HNO₃ ——-> Cd(NO₃)₂ + CO₂ + H₂O

Question 4: What are the harmful effects of cadmium?

Answer:

Cadmium is a chemical element with the formula Cd. It is a naturally occurring metal. It is usually present in the environment as a mineral combined with other metals like oxygen, and chlorine. Breathing high levels of cadmium damages the lungs and can cause death.

Question 5: How do nitrates preserve food?

Answer:

Nitrates are natural chemicals that are found in the soil, air, and water. They are used to prevent or slow down the growth of microorganisms like mold or bacteria.

Question 6: What are the problems with cadmium nitrate?

Answer:

Cadmium Nitrate is a white, odorless crystal that absorbs moisture from the air. It is a strong oxidizing agent highly toxic by ingestion and a known carcinogen.
