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.  [tex](pH=7)[/tex]

If the pH is lower than 7, the solution is acidic.  [tex](pH < 7)[/tex]

If the  pH is higher than 7, the solution is basic.  [tex](pH > 7)[/tex]

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

therefore

The solution is classified as neutral

Answer: The correct answer is Option A.

Explanation:

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

Mathematically,

[tex]pH=-\log [H^+][/tex]

  • 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.
