introduction | rubidium nitrate is colorless cubic rhombus or triclinic crystal, easy to absorb moisture, melting point 310 ℃, relative density 3.11. At 161.4 ℃, rhombic and triclinic crystals are transformed into cubic crystals. Rubidium nitrate is very soluble in water, easily soluble in nitric acid, and slightly soluble in acetone. |
Appearance | Rubidium nitrate is colorless cubic diamond or triclinic crystal |
Preparation | Rubidium nitrate can be prepared by the reaction of rubidium hydroxide or rubidium carbonate and nitric acid. |
fluorescent agent | rubidium nitrate is colorless cubic rhombus or triclinic crystal, chemical formula RbNO3, molecular weight 147.47, easy moisture absorption, melting point 310 ℃, relative density 3.11, from rhombus and triclinic crystal to cubic crystal at 161.4 ℃. Easily soluble in water, easily soluble in nitric acid, slightly soluble in acetone. It can form adduct with nitric acid, such as RbNO3 · HNO3 (melting point 62 ℃) and RbNO3 · 2HNO3 (melting point 45 ℃). Preparation method: It is obtained by dissolving rubidium carbonate in nitric acid, heating to drive out carbon dioxide, and then concentrating and crystallizing. Uses: Used as chemical reagent for microanalysis and fluorescent agent. Rubidium nitrate decomposes and releases oxygen after receiving strong heat, and makes rubidium nitrite. After nitric acid (specific gravity 1.5) is saturated with rubidium nitrate, it is cooled in the ice salt mixture, and a complex of nitric acid and rubidium nitrate is formed. When rubidium nitrate evaporates with excess perchloric acid, rubidium perchlorate crystals are formed. (2016-01-13) |
