NaNO 3 Molar mass: 84.9947 g/mol ... Sodium nitrate is the chemical compound with ... molarities and molalities of aqueous sodium nitrate This page was last edited on ...
One method uses molten sodium nitrate as the salt, and lead which is oxidized, while a more modern method uses scrap iron filings to reduce the nitrate. [4] [84] NaNO 3 + Pb → NaNO 2 + PbO. A more commonly used method involves the general reaction of nitrogen oxides in alkaline aqueous solution, with the addition of a catalyst. The exact ...
The most important sodium compounds are table salt (NaCl), soda ash (Na 2 CO 3), baking soda (NaHCO 3), caustic soda (NaOH), sodium nitrate (NaNO 3), di- and tri-sodium phosphates, sodium thiosulfate (Na 2 S 2 O 3 ·5H 2 O), and borax (Na 2 B 4 O 7 ·10H 2 O). [7] In compounds, sodium is usually ionically bonded to water and anions and is ...
This method is suited for laboratory preparation of sodium azide: 2 NaNO 2 + 2 C 2 H 5 OH + H 2 SO 4 → 2 C 2 H 5 ONO + Na 2 SO 4 + 2 H 2 O C 2 H 5 ONO + N 2 H 4 ·H 2 O + NaOH → NaN 3 + C 2 H 5 OH + 3 H 2 O. Alternatively the salt can be obtained by the reaction of sodium nitrate with sodium amide. [8] 3 NaNH 2 + NaNO 3 → NaN 3 + 3 NaOH ...
The effectiveness of the water gels is dependent on the dissemination of salts in the salt solution. The particles need to be very small and fine so that they can be dispersed well throughout the solution. Some salts that are commonly used include: ammonium nitrate, sodium nitrate, sodium perchlorate and potassium chlorate.
For example, a 40:7:53 mixture of NaNO 2: NaNO 3:KNO 3 melts at 142 °C and is stable to about 600 °C. [4] A minor use is for coloring the light emitted by fireworks: [5] lithium nitrate produces a red color, sodium nitrate produces a yellow/orange color, potassium nitrate and rubidium nitrate produce violet colors, caesium nitrate produces an ...
Excess sodium is distilled from the crude product. [6] A second method involves heating a mixture of sodium azide and sodium nitrate: [6] 5 NaN 3 + NaNO 3 → 3 Na 2 O + 8 N 2. Burning sodium in air produces a mixture of Na 2 O and sodium peroxide (Na 2 O 2). A third much less known method involves heating sodium metal with iron(III) oxide (rust):
Nitratine or nitratite, also known as cubic niter (UK: nitre), soda niter or Chile saltpeter (UK: Chile saltpetre), is a mineral, the naturally occurring form of sodium nitrate, NaNO 3. Chemically it is the sodium analogue of saltpeter. Nitratine crystallizes in the trigonal system, but rarely occurs as well-formed crystals.
