Which of the following pH values is likely to be that of a slightly alkaline solution?
Answer Details
The pH scale ranges from 0 to 14, where 0 is the most acidic and 14 is the most alkaline (basic). A pH value of 7 is considered neutral, meaning that the solution is neither acidic nor alkaline.
So, a slightly alkaline solution would have a pH value greater than 7. Among the given options, only two values are greater than 7: 8 and 13. A pH value of 8 is slightly alkaline, while a pH value of 13 is strongly alkaline.
Therefore, the pH value that is likely to be that of a slightly alkaline solution is 8.
