Aluminum nitrate

Aluminum nitrate is a chemical compound , the aluminum salt of nitric acid . It forms colorless and deliquescent rhombic crystals. Aluminum nitrate is very soluble in water; the solution is acidic. When crystallizing from aqueous solutions, the nona hydrate Al (NO ₃ ) ₃ · 9 H ₂ O is formed. When heated, the hydrate gives off the water of crystallization at 73 ° C. The salt does not have a melting point and decomposes from around 150 ° C.

presentation

The representation of aluminum nitrate can be done by dissolving aluminum hydroxide in nitric acid.

${\displaystyle \mathrm {Al(OH)_{3}\ +\ 3\ HNO_{3}\longrightarrow \ Al(NO_{3})_{3}\ +3\ H_{2}O} }$

use

The fabric was formerly the mantle used -Fabrication. In the manufacture of nuclear fuel rods , the nitrate is used as an extractant for uranium. Furthermore, aluminum nitrate is used as a mordant in dyeing and tanning of leather used.

safety instructions

Aluminum nitrate has a strong irritant effect on the mucous membranes of the eyes and the respiratory tract. In the case of oral intake, the ingested nitrate ions can lead to dizziness, headaches and pain in the abdominal area, bloody vomiting, diarrhea, slackening of the vascular muscles and a reduction in heart rate. The nitrate is a strong oxidizing agent and therefore has a fire-promoting effect.
