I believe, the limiting reagent in this reaction is sodium bicarbonate because my goal is to stop adding hydrochloric acid when all bubbling has ceased. I just want to add just enough hydrochloric acid to react with all of the sodium bicarbonate. 

And the excess reagent is hydrochloric acid since I slowly add droplets of the acid to reach the unreacted sodium bicarbonate (by swirling) and once the bubbling has stopped I have to stop adding acid.

You havent mentioned how much amount you have taken...? Limiting reagent is something which reacts completely in the reaction....without knowing how much you have taken we cant say which is limiting reagent..

anonymous · Answer

1/2 spoonful of sodium bicarbonate

I also have to keep adding droplets of hydrochloric acid till the bubbles have ceased.

anonymous · Answer

So you are adding HCl until the bubble jut ceases..that means you are doing stoichiometric reaction....In theory in that case there is no limiting reagent....it will be more accurate if you  say the amount of moles used...You can not describe quantity as half spoon in science...
