If we were to put baking soda into a cup of vinegar, what would happen? It would fizz up, right?
A good example of this is a science project many children would create, which is a homemade volcano. A paper-mache model of a volcano would be wrapped around a cup and tube of vinegar. When baking soda is poured into the volcano, out comes the fizz. It's a whole lot of fun!
Now let's consider another experiment. But please don't do this at home, only think about this instead. Imagine you had an aquarium of goldfish, and they are your precious pets. Now, imaging pouring a cup of vinegar into the aquarium. What do you think would happen?
It's not that the reaction of the fish would be in bouts of hysteria. If we think about it, we are ACIDIFYING the aquarium with the vinegar. And if the acid of the vinegar reaches the gills of the fish, what do you think would happen to the conversion of the liquid concentrate? The oxygen from the water cannot be used, because the acid takes presidence and becomes the very thing that the fish would be "breathing". We can expect a dead fish or a sick fish as a result.
