Aluminium nitrate is a white, water-soluble salt of aluminium and nitric acid, most commonly existing as the crystalline hydrate, aluminium nitrate nonahydrate, Al(NO 3) 3 ·9H 2 O. Preparation [ edit ]
The nitrate ion. Alkali metal nitrates are chemical compounds consisting of an alkali metal (lithium, sodium, potassium, rubidium and caesium) and the nitrate ion. Only two are of major commercial value, the sodium and potassium salts. [1] They are white, water-soluble salts with melting points ranging from 255 °C (LiNO 3) to 414 °C (CsNO
When hydrated aluminium nitrate reacts with dinitrogen pentoxide it forms a nitronium salt: [NO 2] + [Al(NO 3) 4] −. [2]A way to make a tetranitratoaluminate salt of a cation is to treat the chloride of the cation and aluminium chloride with liquid dinitrogen tetroxide pure or dissolved in nitromethane.
The Weight Watchers diet tries to restrict energy to achieve a weight loss of 0.5 to 1.0 kg per week, [1] [3] which is the medically accepted standard rate of a viable weight loss strategy. [4] The dietary composition is akin to low-fat diets [ 1 ] or moderate-fat and low-carbohydrate diet [ 5 ] depending on the variant used.
Nitrate is a polyatomic ion with the chemical formula NO − 3. Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. [1] Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate.
Lebanese authorities said 2,750 tonnes of ammonium nitrate had been stored for years at the Beirut port without safety measures. * Ammonium nitrate is an industrial chemical commonly used in ...
A variety of compounds of empirical formula AlR 3 and AlR 1.5 Cl 1.5 exist. [22] The aluminium trialkyls and triaryls are reactive, volatile, and colorless liquids or low-melting solids. They catch fire spontaneously in air and react with water, thus necessitating precautions when handling them.
The origin of spontaneous polarization is the strong ionic character of chemical bonds in wurtzite AlN due to the large difference in electronegativity between aluminium and nitrogen atoms. Furthermore, the non-centrosymmetric wurtzite crystal structure gives rise to a net polarization along the c-axis.
