This is a chemical equation describing the reaction process between CrCl3 (Chloride chromium) and H2O (water) to produce Cr(OH)3 (Chromium hydroxide) and HCl (Hydrochloric acid).
According to the law of conservation of mass, the number of moles of the reactants and the number of moles of the products must be equal. Here, we have 2 moles of CrCl3 reacting with 3 moles of H2O to form 2 moles of Cr(OH)3 and 6 moles of HCl.
- Reaction Conditions
This reaction usually occurs at normal temperature and pressure conditions.
- Reaction Process
When CrCl3 comes into contact with water, it undergoes hydrolysis to form chromium hydroxide and hydrochloric acid.
- Phenomena Occurring
During the reaction, one can observe a change in the color of the solution. Initially, the CrCl3 solution is green, but after the reaction, the solution turns to the reddish-brown of Cr(OH)3. At the same time, HCl gas is produced, which can be detected by its characteristic odor.
