pH stands for “potential of hydrogen.” It’s just measuring how many hydrogen ions are floating around. More hydrogen ions = more acidic. Fewer = more alkaline. It’s like a party: too many guests (ions) and things get crazy and sour.

Remember that logarithm thing from school? Yeah, pH is logarithmic, which means a jump from 7 to 6 is ten times more acidic. From 7 to 5? That’s 100 times more acidic. Mind-blowing, right?

So a little change on the scale is a huge change in reality. Your water might be plotting something without you knowing.

Tap Water vs. Bottled Water: The Showdown

Tap water usually falls between 6.5 and 8.5, depending on where you live. That’s perfectly fine—your local water plant has to follow rules. It’s like they’re the bodyguard of your water.

Bottled water? Oh, it’s a wild card. Some brands are acidic (like 4.5) because of added carbonation or fancy “purification” tricks. Others brag about being “alkaline” at 9 or 10. It’s a marketing circus.
