Filter the Ba(NO3)2 solution to remove any iron impurities, then evaporate it to obtain solid crystals.Īnother method is to react barium sulfide with nitric acid. This produces Ba(NO3)2 and carbon dioxide. One method is to react barium carbonate with nitric acid. LD50 (oral, rat) = 355 mg/kg LC50 (inhalation, rat) = 0.15 mg/L/4hĭifferent methods can be used to create Ba(NO3)2, which is a white solid substance. S36/37/39: Wear suitable protective clothing, gloves and eye/face protection. S26: In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. S17: Keep away from combustible material. S13: Keep away from food, drink and animal feeding stuffs. You can also take sulfate salts to reduce the toxicity of barium.
BARIUM NITRATE PRECIPITATE SKIN
If you get exposed to Ba(NO3)2, you should rinse your eyes and skin with water and seek medical help. You should also keep it away from heat, sparks, flames, and combustible materials. You should avoid contact with Ba(NO3)2 and wear protective equipment when handling it. Ba(NO3)2 can also cause muscle spasms, heart problems, and death. It can irritate your eyes, skin, and respiratory system. It can harm you if you swallow it or breathe it in. Soluble in ethanol, acetone, and methanol insoluble in ether and chloroformīa(NO3)2 is a toxic and oxidizing substance. The solubility increases with increasing temperature and decreases with increasing pressure.īa(NO3)2 is also soluble in other solvents, such as ethanol, acetone, and methanol, but less soluble than in water. This means that 34 g of Ba(NO3)2 can dissolve in 100 ml of water at this condition. The solubility depends on several factors, such as temperature, pressure, and the presence of other substances in the solution.Īt 20☌ and atmospheric pressure, the solubility of Ba(NO3)2 in water is about 34 g per 100 ml. The solubility of Ba(NO3)2 is the amount of Ba(NO3)2 that can dissolve in a given amount of solvent, usually water. The length of each edge of the unit cell is 0.65 nm. The coordination number of each ion is six, which means each ion is surrounded by six oppositely charged ions. The structure of Ba(NO3)2 can be represented by a unit cell, which is the smallest repeating unit that shows the arrangement of ions in a crystal lattice.Ī unit cell of Ba(NO3)2 has a cubic shape, with one barium ion at each corner and one nitrate ion at the center of each face. Ba(NO3)2 is an ionic compound, which means it consists of positively charged barium ions and negatively charged nitrate ions held together by electrostatic forces. The structure of Ba(NO3)2 shows how the atoms and ions are arranged in space. Molecular weight refers to the average mass of one molecule of a substance, while molar mass refers to the mass of one mole of a substance. Sometimes, the term molecular weight is used interchangeably with molar mass, but they are not exactly the same. It is the mass of one mole of Ba(NO3)2 molecules. The molecular weight of Ba(NO3)2 is the same as its molar mass, which is 261.337 g/mol. To calculate it, we need to divide the mass of a sample of Ba(NO3)2 by its volume:įor example, if we have a sample of 10 g of Ba(NO3)2 and its volume is 3.1 ml, then its density is:ĭensity of Ba(NO3)2 = 10 / 3.1 = 3.23 g/ml Barium Nitrate Molecular Weight It is the mass per unit volume of Ba(NO3)2. Ba(NO3)2 is a white crystalline solid at room temperature and pressure, but it melts when heated above its melting point. It is the temperature at which Ba(NO3)2 changes from solid to liquid. However, Ba(NO3)2 decomposes before reaching its boiling point, so it is not possible to boil it without breaking it down into other substances. It is the temperature at which Ba(NO3)2 changes from liquid to gas. To calculate it, we need to add the atomic masses of all the atoms in the formula: The molar mass of Ba(NO3)2 is 261.337 g/mol. The nitrate ion has a charge of -1 and the barium ion has a charge of +2, so they combine in a 1:2 ratio to form a neutral compound. It shows that one molecule of barium nitrate consists of one atom of barium and two molecules of nitrate. The molecular formula of barium nitrate is Ba(NO3)2. IUPAC nameīarium nitrate, Bariumdinitrat, Dinitrate de baryum, CQ9625000, (nitrooxy)bario nitrateīarium Nitrate Properties Barium Nitrate Formula It can explode when heated or mixed with combustibles. It dissolves in water and forms barium and nitrate ions. Barium nitrate (Ba(NO3)2) is a white solid.
