What number on the pH scale indicates that someone is slightly alkaline?

6-7
7-8
8-9
9-10

The correct answer is: 8-9

The pH scale ranges from 0 to 14, where 7 is considered neutral. Values below 7 represent acidic conditions, while values above 7 indicate alkalinity. A pH of 8 to 9 suggests that a substance is slightly alkaline. This range reflects a modest increase in pH above neutral, aligning with the definition of being slightly alkaline. Because 8 to 9 falls within the boundaries that categorize a solution as having an alkaline character, this is the correct choice. The other choices indicate varying degrees of acidity or alkalinity. A range of 6 to 7 is acidic to neutral, while 7 to 8 is only slightly alkaline, thus not fully capturing the essence of being slightly alkaline. A range of 9 to 10 suggests a stronger alkaline condition, which extends beyond the 'slightly' classification, making it not appropriate for the question.
