pH is just a way to measure how acidic or basic something is. Acidic is like a sour lemon—low pH (around 2). Basic (or alkaline) is like baking soda—high pH (around 8 or 9).
And right in the middle? Pure water at pH 7. That’s neutral, the chill friend who doesn’t take sides. Everything else is either a sour pucker or a slippery soap bar.
So an alkaline pH is anything above 7. But don’t go thinking it’s the same as “healthy” or “magical.” Life is weirdly complicated, I know.
