What is Cr(NO3)3? Important knowledge about Cr(NO3)3.

  1. Definition of Cr(NO3)3

Cr(NO3)3, also known as Chromium Nitrate or Chromium (III) Nitrate, is a chemical compound formed from Chromium and Nitrate. The English name of this compound is Chromium Nitrate. Cr(NO3)3 is a solid substance with colors ranging from pink to red depending on the temperature and humidity. The molar mass of Cr(NO3)3 is 238.01 g/mol, consisting of one chromium ion (Cr3+) and three nitrate ions (NO3-).

  1. Properties: Cr(NO3)3

Cr(NO3)3 has quite distinctive physical properties. It is a solid substance with colors ranging from pink to red. Its smell is quite unique, indescribable. The PH value of Cr(NO3)3 is between 1-3, indicating that it is a strong acid. Cr(NO3)3 also has strong oxidizing properties, readily reacting with reducing agents.

  1. Common chemical equations involving Cr(NO3)3

Cr(NO3)3 can react with metals such as Fe, Al to form Cr and simultaneously reduce nitrate concentration. It can also react with strong acids like H2SO4, HCl to produce NO2 gas. In addition, Cr(NO3)3 can react with water to form the ion [Cr(H2O)6]3+ and nitrate.

  1. Synthesis of Cr(NO3)3

In the laboratory, Cr(NO3)3 is usually synthesized by reacting Chromium with concentrated Nitric Acid. In industrial processes, Cr(NO3)3 is formed by reacting Chromium with Nitric Acid under high temperature and pressure conditions.
