WebThe pH scale measures how acidic or basic a substance is. The scale ranges from 0 to 14 and is based on the concentration of hydrogen ions in a solution. Pure or distilled water is neutral—it has an equal number of hydrogen and hydroxide ions—so it falls at the middle of the scale with a pH of 7. WebThe pH value can be less than 0 for very concentrated strong acids or greater than 14 for very concentrated strong bases. The pH scale is traceable to a set of standard solutions …
