Consider the following equation:
Cl2 (g) + 2OH- (aq.) -----------> Cl- (aq.) + OCl- (aq.) + H2O (l) --------- 1
OCl- (aq.) + H2O (l) -----------> OH- (aq.) + HOCl (aq.) ------------------- 2
By subtitution,
Sub 2 into 1:
Cl2 (g) + 2OH- (aq.) ----------> Cl- (aq.) + OH- (aq.) + HOCl (aq.)

✔ 最佳答案
The two equations represent two independent reactions.
Cl2(g) + 2OH-(aq) → Cl-(aq) + OCl-(aq) + H2O(l) ------ 1
The above equation shows the reaction between chlorine gas and an
OCl-(aq) + H2O (l) → OH-(aq) + HOCl (aq.) ------ 2
The above equation shows the reaction of the hydrolysis of OCl-(aq) ion in a neutral solution.
Since the two reactions are independent, it is thus meaningless to combine these two equations by means of any method.
