FOOTE AND MOHLER: IONIZATION 44 1 



Adding : 



(HgClo) + QhsCU - ^Hg + 5Hg + /'hs + 2^01 - 2Eci " SusCh = 



(Hg)++ + 2(C1)- (5) 



For the ionization of (HgClo) into (HgCl)+ and (CI)- we ob- 

 tain: 



[HgCl2] + QngCb = Hg + (CI2) 



Hg + V2(Cl2) - Qngci = [HgCl] 



(HgCl2) - 5HgCl. = [HgCl2] 



[HgCl] + 5Hgci = (HgCl) 



(HgCl) + /HgCl = (HgCl) + 



72(02) + Dcx = (CI) 



(CD- - Eci = (Cl)- 

 Adding : 



(HgCl2) + QugCh — QngCl — 5"HgCl2 + -SHgCl + 



/HgCl + -Del - Ed = (HgCl)+ + (CI)- (6) 

 For the ionization of (HgCl) into (Hg)+ and (CI)- we obtain: 

 [HgCl] + Qngci = Hg + V2(Cl2) 

 Hg - Lng = [Hg] 



[Hg] + 5Hg = (Hg) 



V2(Cl2) + i^c. = (CI) 

 (Cl)-itci = (Cl)- 



(Hg) + Jug = (Hg) + 

 (HgCl) - 5Hgci = [HgCl] 

 Adding : 

 (HgCl) + Qngci - Lu, + 5Hg + /Kg + Del - 



Eci -5Hgci = (Hg)++ (CI)- (7) 

 The works of ionization in the manner indicated are given by- 

 equations (5), (6) and (7). Accordingly 



J'ugch = Qngch — ^Hg + ^Hg + J'ng + 2Da. — 



2Eci - SngCh (8) 



JugCh = QngCb ~ ^HgCl ~ ^S^HgCh + -S^HgCl + 



/HgCl + ^Cl - Ecl (9) 



/'HgCi = QHgCi — Lhs + Sng + Jug + Del — Ecl — Sugci (10) 



The heats of sublimation may be derived from the vapor 

 pressure data by means of the formula*^: 



p^T = Ce~^^^'^, where R = 1.985 g. cal.
