What does pH measure and why does it matter?
pH is a tiny score with a big job: it tells you how acidic or basic a water-based liquid is. If that sounds abstract, here’s the friendly version. pH is a way of asking, “How many extra sharp little hydrogen bits are swimming around in here?”
In acidic liquids, there are more of those hydrogen bits, called hydrogen ions. In basic liquids, there are fewer. Neutral is the middle ground. Pure water sits close to that middle, which is pH 7.
