Which statement is true about a neutral solution? its ph is less than 7. its ph is greater than 7. it has the same concentration of hydronium and hydroxide ions. it has a greater concentration of hydroxide ion than hydronium ions.

Option C It has the same concentration of hydronium and hydroxide ions is correct.

Explanation:

A neutral solution will have pH=7

and the concentration of hydronium ions and hydroixde ions is the same.

So, Option C It has the same concentration of hydronium and hydroxide ions

is correct.

Option (c) is the correct answer.

Explanation:

A solution whose pH is less than 7 is known as an acidic solution. In this solution, concentration of hydrogen ions is more than hydroxide ions.

Whereas a solution whose pH is more than 7 is known as a basic solution. In this solution, concentration of hydroxide ions is more than hydrogen ions.

On the other hand, when pH of a solution is equal to 7 then the solution will be known as neutral solution. That is, the concentration of both hydrogen and hydroxide ions is same in a neutral solution.

Thus, we can conclude that the statement it has the same concentration of hydronium and hydroxide ions, is true about a neutral solution.
