What is the theoretical yield of hydrochloric acid ? grams What is the percent yield of hydrochloric acid ? %
For the following reaction, 4.91 grams of water are mixed with excess chlorine gas. The reaction yields 12.5 grams of hydrochloric acid.
chlorine (g) + water (l) hydrochloric acid (aq) + chloric acid (HClO3) (aq)
| What is the theoretical yield of hydrochloric acid ? | grams |
| What is the percent yield of hydrochloric acid ? | % |
Actual yield :- Amount of product produced actually after the reaction is complete.
Theoretical yield :- Amount of product that could have been produced if everything would have gone perfectly.
Given reaction :-
chlorine (g) + water (l) hydrochloric acid (aq) + chloric acid (HClO3) (aq)
Note :- Since, chlorine is in excess therefore it is a excess reagent and can be ignored.
So, water is the limiting reagent here.
Now, lets calculate the theoretical yield :
(4.91gms water)( 1 mol H20)(18 gm H20 ))(1 mol HCl/1 mol H20)(36.46 gm HCl/ 1 mol HCl)
= 9.8 gm HCl
