Answer: The correct answer is Option A.

Step-by-step explanation:

pH is defined as the negative logarithm of hydrogen ion concentration present in the solution.

Mathematically,

$pH=-\log [H^+]$

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.

Answer:

Option A. neutral

Step-by-step 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.
(pH=7)

If the pH is lower than 7, the solution is acidic.
(pH < 7)

If the pH is higher than 7, the solution is basic.
(pH > 7)

In this problem we have a solution that has a pH=7

therefore

The solution is classified as neutral
