The Ph in the chemistry test used to test the acidity of substances stands for 'potential hydrogen,' as in how much hydrogen is in each of the substances being tested. Learn what Ph stands for when testing for acids and bases in this free video on chemistry experiments from a science teacher.

Okay, what would you check these chemicals with? And what we're going to do is we're going to check the PH Balance and by the way, PH means potential of hydrogen. How much hydrogen is in these? And what you can do is one way you can check is litmus paper and you might notice this, it's kind of from how you would check your pool acid. Litmus paper is made out of something that's so completely natural. And what it is, is it actually tells you some indicators on the top here. But, it's a plant that's actually found in South America and it's called the, the plant is called the rocella tinctoria. If you can even pronounce that. And actually it's found in different places, but mainly it's found in South America. And that's one way to check for the acidity base where you would put this into one of these and then it would give you a color indicator. What we're going to do is that, if this is not available to you and this is not readily available to everybody, you can make your own indicator and that's out of cabbages, red cabbages that is. So that's what we're going to do next is make our own indicator.
