An unknown solution has a pH of 7. how would you classify this solution?
2 answers:
Answer:
Option A. neutral
Explanation:
we know that
The pH is a number that describe the concentration of hydrogen ions in the solution. A solution's pH will be a number between 0 and 14.
A solution with a pH of 7 is classified as neutral.
If the pH is lower than 7, the solution is acidic.
If the pH is higher than 7, the solution is basic.
In this problem we have a solution that has a pH=7
therefore
The solution is classified as neutral
<u>Answer:</u> The correct answer is Option A.
<u>Explanation:</u>
pH is defined as the negative logarithm of hydrogen ion concentration present in the solution.
Mathematically,
- If the solution has high hydrogen ion concentration, then the pH will be low and the solution will be acidic. The pH range of acidic solution is 0 to 6.9
- If the solution has low hydrogen ion concentration, then the pH will be high and the solution will be basic. The pH range of basic solution is 7.1 to 14
- The solution having pH equal to 7 is termed as neutral solution.
Hence, the correct answer is Option A.
