To determine which of the given pH values corresponds to a neutral solution, let's review the concept of pH in the context of chemistry. The pH scale measures how acidic or basic a solution is, and it ranges from 0 to 14.
- A pH value less than 7 indicates an acidic solution.
- A pH value greater than 7 indicates a basic (or alkaline) solution.
- A pH value of exactly 7 is considered neutral.
In other words, pure water has a pH of 7, which is neutral because it is neither acidic nor basic.
Given the options:
A. 2
B. 4
C. 7
D. 9
Option A (2) falls into the acidic range.
Option B (4) also falls into the acidic range.
Option D (9) falls into the basic range.
Therefore, the neutral pH, which is 7, corresponds to Option C.
The pH of a neutral solution, according to the given options, is:
C. 7
And since the result from analyzing the information provided is the number 3, which corresponds to Option C in the given list, the answer is:
C. 7
