Question: What is the difference between an acid and a base?
Answer: An acid donates a hydrogen atom and a base accepts a hydrogen atom.
To remember the answer to this CC science fact, Catherine and I talked about keeping the words acid and base in order then remembering that "it is better to give than to receive." Therefore the acid gives and the base receives the hydrogen atom.
So then Catherine tells me, "Mom, here's an acid thing that I did.... And the other day I did a different acid thing," and tells me how she was a giving person.
Makes sense to me!
