when acidified potassium dichromate (VI) is added to iron(II) sulfate why does a redox reaction occur?
How about if ammonia is added to iron(II) sulfate?
The dichromate is oxidized, so it needs H+ ions in solution to form water.
One the second "question", I miss your question; are you referring to Mohr's Salt? I really don't know what you are asking.
