sodium nitrates

The common name of sodium nitrate is "Chile salt Petre". It is found in large quantity in Chile in South America. It can be prepared by treating the oxide, hydroxide, carbonate or hydrogen carbonate salts of sodium with nitric acid. It is a colorless crystalline solid..

By Treating Metals with Nitric Acid The reaction of nitric acid with sodium, potassium and calcium is too explosive. Hence, these metals cannot be used to prepare their nitrates. ..

Sodium extract (or Lassaigne's extract) is boiled with dilute nitric acid to decompose sodium cyanide or sodium sulphide (if present) to hydrogen cyanide and hydrogen sulphide gases, respectively. This solution is cooled and silver nitrate solution added. A ..

Metallic nitrates, when heated, give out oxygen. At the same time, most of them also give out a reddish brown gas - nitrogen dioxide, NO2. Thus, these nitrates cannot be used to prepare oxygen. However, sodium and potassium nitrates do not produce nitro..

Solids with a definite geometric pattern. Examples: Iron, copper, silver, sulphur etc. are some elements which form crystalline solids. Potassium chloride, sodium nitrate etc are some of the compounds, which are crystalli..

The presence of halogens in any organic compound is detected by using sodium extract (Lassaigne's extract) with silver nitrate as follow..

Solubility is the ability of a solute to dissolve in a solvent. To explain this, consider the following case. Three students A, B and C are given 3 beakers, each containing 100 g of water at 20 o C. They are also given one salt each. Student A is given potassium nitrate, Student B is give..
