3HCl + HNO3 --------> NOCl + 2H2O + 2Cl
If anybody know why it is Cl (not Cl2) in this reaction? What does Cl mean?
Also I want to know how aqua regia solves Au?
-
Au (s) + 3 NO3- (aq) + 6 H+ (aq) ? Au3+ (aq) + 3 NO2 (g) + 3 H2O (l)
Au3+ (aq) + 4 Cl- (aq) ? AuCl4- (aq)
And you are correct, it must be Cl2
All very well explained here (http://en.wikipedia.org/wiki/Aqua_regia), google usually helps ;)
-
If the Chlorine is in statu nascendi you can write it as "Cl".
-
in statu nascendi
"in the state of being born"
Just as something is about to begin.
The above is for those who are Latin challenged like me.
