color of hexaammincobalt(II) ion
« on: May 05, 2004, 08:14:06 PM »
Hi,

Can someone tell me the most common colour of hexaammincobalt(II) ion [Co(NH3)6]2+ ?

Does it take a blue colour ? if so on which conditions ?

Depends on your counterion.  The chloride counterion produces rose-red crystals according to the CRC, but there's a lot more complex salts that can be made.  Could you give a little more information?

It's a book, you can find it at most libraries or ask them to get a copy for the library "CRC Handbook of Chemistry and Physics"
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
