PH levels

This afternoon in class we learnt how to use a tablet. We had to research about PH levels. This is what we found...

PH levels show whether something is either acid or base. The numbers on top of the scale shows that the item is base, and the numbers at the bottom show whether the item is acid. Numbers around 7 are neutral.
