Yesterday we conducted the Formula of a Chloride Lab in first hour. We prepared our reactants after weighing them and then mixed the Zinc pebble with the 11.25 ml of M3 HCl and it produced a somewhat violent reaction. The piece of zinc started to break up and then started fizzing and bubbling. It was interesting to watch the small pieces of zinc all bubbling at once but then I started to get a headache. I was not even close to the beaker with the watch glass on top and it was still burning my nose. This was the only drawback, but it was still a very fun lab to participate in.
Above is a picture of the Zinc having an exothermic reaction with the HCl.
This was towards the end of the reaction whenever the acid started to finally be driven off.
This was right before we removed the beaker from the hotplate. The piece of zinc was completely gone and so was all the hydrochloric acid. This reaction yielded ZnCl2.
What did you get for the final answer? Our answer was off by a large margin, but I'm curious to see what other people got for that.
