Why Do Acids Burn?

You can feel the tingle of lemon in your mouth as the acid reacts with the surrounding tissue and receptors. You've probably seen how soda can dissolve a piece of meat after a couple days. But what's so special about these substances that it can seemingly eat away material on their own?

Edit: @1:06 it says "Energy" a better word should have been "strength".
