When I'm preparing a salt
for e.g. I add excess magnesium to hydrochloric acid
and the questions asks why the reaction stopped
Do I say because all the magnesium has reacted or because all the acid has reacted?
Why did the chemical reaction stop?

✔ 最佳答案
As it has been stated that magnesium is in excess, then hydrochloric acid is the limiting reactant.Hence, the reaction stops when all the acid has reacted.

Could be either --- so in general you say that all of ONE of the reactants has been used in the reaction. ... Unless you have some amounts and then they want you to do a calculation to show which has been used up to stope the reaction.
