Here’s how you can prove it without a chemistry degree. Grab a spoonful of baking soda and dump it into a cup of vinegar. Whoa—look at that volcano! All those bubbles? That’s the base (baking soda) and the acid (vinegar) having a violent argument. The result: salt, water, and carbon dioxide gas—a fizzy peace treaty.
If baking soda were an acid, it would just sit there like a sad, wet sock. No drama, no fizz, just disappointment. So whenever you see that foam, remember: you just watched chemistry’s version of a rock concert.
