If someone held out their hand and said to you, “Can you please pass me the litmus paper strips?” would you know what they are talking about? Where would that happen, anyway? It's good to know; you can't be "neutral" about it!

Substances can be identified as an acid, a base, or neutral, by dipping them into red cabbage juice.

Really? You may think this sounds odd — plus, making cabbage juice every time you want to test a substance is a lot of work!

Before we find out, if you missed or want to review the previous Acids and Bases lessons, you can find them in the Related Lessons in the right-hand sidebar.

Let’s join Dr. Z to see what he is “cooking up” in his lab today and see if we can get these questions answered!
