Ph measurement meaning
Webb8 apr. 2024 · pH measures the number of hydrogen ions in a solution and it tells us whether a solution is an acid or a base. The pH scale ranges from 0 to 14. Any solution that has a pH from 1 to 6 is acidic, any solution with a pH value of 7 is neutral and any solution with a pH value between 8 to 14 is basic.
