Types of Chemical Reactions

 

There are several types of common chemical reactions that you need to know.

With some reactions you can’t be sure if you’ve made the right product,

especially if the product is a colorless gas like carbon dioxide, so you also

need to know how to test for its presence.

 

Metal-Acid Reactions


As in acid-base reactions, a metal-acid reaction will create a salt. However,

water will not be produced and hydrogen will be produced.

 

metal + acid               salt + hydrogen

 

If we use sulfuric acid and zinc as our examples, this would be the word

equation:

 

zinc + sulfuric acid      zinc sulfate + hydrogen

 

In order to test for the presence of the hydrogen (it’s a colorless gas), we

have to place a lit splint inside the test tube, as soon as the reaction is over.

There should be a ‘squeaky pop’ sound. If we wait too long, the gas will have

escaped and there will be no sound.
