Detailed information about the equation 2HNO3 + Co -> 2NO2 + 2H2O + Co(NO3)2:
This equation describes the chemical reaction process between nitric acid (HNO3) and cobalt (Co). The result of this reaction is the formation of nitrogen dioxide (NO2), water (H2O), and cobalt nitrate (Co(NO3)2). -
Reaction conditions:
The reaction requires standard temperature and pressure. Nitric acid needs to have a high enough concentration for the reaction to occur. Additionally, cobalt must be in pure form for the reaction to take place. -
Reaction Process:
-
Phenomena occurring:
During the reaction process, you can observe the color change of the solution from colorless (nitric acid) and bright red (cobalt) to brown (nitrogen dioxide), along with the formation of water droplets. Additionally, the formation of cobalt nitrate also results in a color change from the colorless nitric acid to the green of cobalt nitrate.
