Mg(NO3)2 Uses (Magnesium nitrate)

Magnesium nitrate is used as a dehydrating agent to prepare concentrated nitric acid.Used in the manufacturing of petrochemicals.Used as a desensitizer for lithographic plates.Used to lớn manufacture ammonium nitrate.Used in the purification of nitric acid.Used in industries as a viscosity adjuster.Used in the manufacturing of agricultural products.Used in the making of toner, and colourant products.Used in the process is mining.

Magnesium nitrate Reactions

Magnesium dinitrate reacts with alkali metal hydroxide lớn produce the following:

Mg(NO3)2 + 2 NaOH → Mg(OH)2 + 2 NaNO3

Magnesium nitrate has a high affinity towards water. Therefore, heating it results lớn decompose into magnesium oxide, nitrogen oxides, và oxygen.

2 Mg(NO3)2 → 2 MgO + 4 NO2 + O2.

Health Hazards

Exposure to Magniosan causes mild irritation in the mucous membranes. Symptoms include shortness of breath & coughing. Swallowing large doses may result in dizziness, vomiting, weakness, collapse. Abdominal pain, bloody diarrhea, và convulsions. When comes in tương tác with skin causes redness, pain, và irritation.

On heating this compound lớn decompose it emits toxic fumes of nitrogen oxides. Tương tác with oxidizable compound may result in extremely violent combustion.

Frequently Asked Questions

What is magnesium nitrate used for?

Often used in pyrotechnics is magnesium nitrate; và in the manufacture of concentrated nitric acid where it extracts water and concentrates the acid vapours khổng lồ 90–95 percent HNO3. It is also used to help in the processing of ammonium nitrate for coating và prilling.

Is magnesium nitrate acid or base?

Magnesium nitrate is a crystalline source with high water solubility for use consistent with nitrates and lower (acidic) pH. Nitrate compounds are usually soluble in water. Even the nitrate products are oxidizing agents. The nitrate compounds can form a flammable mixture when combined with hydrocarbons.

What type of compound is magnesium nitrate?

Magnesium Nitrate is an ionic compound formed by cation Magnesium Mg2+, and polyatomic anion Nitrate NO3–. The charges must be equal & the opposite in order for these two ions lớn bind. Therefore, the one + 2 magnesium ion would require two -1 nitrate ions khổng lồ balance.

What metal will react with magnesium nitrate?

Zinc, copper, & lead vì not react with magnesium nitrate because in the activity sequence magnesium is higher, because it is more reactive than other metals. Therefore, none of zinc, copper, or lead will displace magnesium ions from solution, so that there will be no reaction.
