Reaction equation for titration of sodium cyanide with nickel nitrate
Thread Content
Please tell me how to write the reaction equation for the titration of sodium cyanide with nickel nitrate using butanedioxime as indicator in ammoniacal medium. Thank you. This post was last edited by Canghai Yisha on 2009-2-10 10:09 ]

This is an English website. Is it available in Chinese?
I seem to have read in a book that dihomoxime is used as an indicator and nickel nitrate is used to titrate sodium cyanide. It is possible that nickel ions first form a certain proportion of complexes with sodium cyanide. After the reaction is completed, excess nickel ions and dihomoxime form a red complex. The reaction only generates complexes and no other reactions occur.
I found a national standard for sodium cyanide. The analysis principle is given in it: The link is: http://bbs.hcbbs.com/viewthread.php?tid=14078
There is no reaction equation in the national standard. What the fifth floor said seems to make sense. I wonder if you can introduce it in more detail? :lol :lol
