Why it is Cl (not Cl2) ?
« on: November 11, 2006, 01:26:53 PM »
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, 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.
