What Is the Ph of Hard Waterの主要なニュースを専門的かつ分かりやすくまとめました。全体像を一目で把握できます。

First, a quick chemistry refresher—don’t worry, I’ll make it painless. The pH scale runs from 0 to 14, where 7 is perfectly neutral (like pure water, which is a total wallflower). Numbers below 7 are acidic (think lemon juice or your mood after a bad haircut), and numbers above 7 are alkaline or basic (like baking soda or your grandma’s “I’m fine” smile). So where does hard water land? Brace yourself: it’s usually right around 7.5 to 8.5—mildly alkaline. Thrilling, right?
