the chemical formula for nitrite is NO2 and for nitrate is NO3 but why for copper nitrite is Cu(NO3)2
The compound you're talking about, Cu(NO3)2, is called Copper (II) Nitrate according to Wikipedia. Yes, the NO3 radical is always termed nitrate, in my opinion.
Cu(NO3)2 is actually copper nitrate and not nitrite.you got wrong information buddy.
Copper nitrite is not Cu(NO3)2 - This is copper (11) nitrate .If it contains the NO3- ion it must be a nitrate. You may have been confused by a question and answer that appeared in Yahoo ! Answers 6 years ago What is the formula for copper nitrite? The answer given ( and voted as best answer by 2 voters ) was: Copper Nitrite = Cu(NO3)2 In addition the asker also added : What is the formula for manganese bromate : with the reply Manganese(II) Bromate = MnBr (not to be confused with Manganese Bromide = MnBr2). I leave you to draw your own conclusions about the chemistry ability of the answerer. Edit after your additional comments : I do not know why you are asking this question: You know that the NO2- ion is the nitrite ion Your book tells you that copper nitrite is Cu(NO2)2 Why then do you ask : nitrate is NO3 but why for copper nitrite is Cu(NO3)2
