pH is just a fancy way to say “potential of hydrogen.” Sounds intimidating, but it’s not. Think of it as a scale from 0 to 14 that measures how acidic or basic something is.
If it’s super acidic (like lemon juice), it’s low on the scale—around a 2. If it’s very basic (like bleach), it’s high—around a 12. Your water? It’s supposed to be a boring, perfect 7.
Well, almost perfect. But we’ll get to that in a second. You’re probably wondering, “Why should I care about a number that I can’t even see?” Good question, friend.
The Sweet Spot for Your Tap Water
Regulators (the people who keep your water from tasting like a swamp) have a rule. Potable water should have a pH between 6.5 and 8.5. That’s the official “safe zone.”
Why the wiggle room? Because water is a wild card. It picks up stuff from the ground, the pipes, and even the air. A little shift is normal—like a mood swing, but for H₂O.
If it’s below 6.5, your water is acidic. That can make it taste metallic and even start eating your copper pipes. Yikes. If it’s above 8.5, it’s basic (also called alkaline). That can taste bitter, like a bad cup of coffee.
