Sn(no3)2?Sn NO3 2 is a white, crystalline solid used in the manufacture of pyrotechnics, as a mordant in dyeing, and as an antiseptic. It is also known as stannous nitrate or tin(II) nitrate.
Sn NO3 2 is produced by the reaction of tin(II) oxide with nitric acid:
SnO + 2 HNO3 → Sn(NO3)2 + H2O
The resulting solution is typically diluted with water before use.
Sn NO3 2 is used as a mordant in dyeing and printing fabrics. It helps to fix the dye to the fabric, making the colors more resistant to fading.
It is also used in pyrotechnics, where it provides bright white light when burned.
Sn NO3 2 can help prevent bacteria and fungi growth when used as an antiseptic. It is commonly used in mouthwashes and toothpaste.
Sn NO3 2 is a strong oxidizing agent and should be handled with care. It can irritate the skin and eyes. If ingested, it can be harmful or fatal.
Sodium nitrate is a compound with the chemical formula NaNO3. It is a white, crystalline solid that is very soluble in water. Sodium nitrate is used as a food preservative, as an oxidizing agent, and in the manufacture of explosives and fertilizers. However, it can be harmful if inhaled or ingested in large quantities.
When heated, sodium nitrate decomposes to form sodium oxide and nitrogen dioxide:
2 NaNO3 → 2 Na2O + 4 NO2
If strongly heated, sodium nitrate will decompose even further to form sodium peroxide, oxygen gas, and nitrogen dioxide:
4 NaNO3 → 2 Na2O2 + 4 NO2 + O2
Sodium nitrate is a strong oxidizing agent and can ignite combustible materials. Therefore, it should be stored in a cool, dry place away from flammable materials.
