My First Experience with Chemical Reactions
by Ira Remsen—Chemistry:The Central Science
While reading a textbook of chemistry,I came upon the statement ‘nitric acid acts upon copper,’ and I determined to see what this meant.Having located some nitric acid,I had only to learn what the words ‘a(chǎn)ct upon’ meant.In the interest of knowledge I was even willing to sacrifice one of the few copper cents then in my possession.I put one of them on the table,opened a bottle labeled “nitric acid,” poured some of the liquid on the copper,and prepared to make an observation.But what was this wonderful thing which I beheld?The cent was already changed,and it was no small change either.A greenish-blue liquid foamed and fumed over the cent and over the table.The air became colored dark red.How could stop this?I tried by picking the cent up and throwing it out the window.I learned another fact:nitric acid acts upon fingers.The pain led to another unpremeditated experiment.I drew my fingers across my trousers and discovered nitric acid acts upon trousers.That was the most impressive experiment I have ever performed.I tell of it even now with interest.It was a revelation to me.Plainly the only way to learn about such remarkable kinds of action is to see the results,to the experiment,to work in the laboratory.
