The hydrogen ion concentration is 1 × 10-7. what is the ph of this solution?

The pH of the solution is 7

Explanation:

The pH is a measure of the acidity of the solutions. It is defined as the negative logarithm of the molar concentration of hydrogen ions (H⁺).

pH = - log [H⁺]

The hydrogen ion concentration of this solution is 1 × 10⁻⁷ M.

Hence:

pH = - log (1 × 10⁻⁷) = - (-7) = 7

This pH corresponds to a neutral solution (neither acid nor alkaline).

You should remember this relation bwtween pH and acidity/alkaliinity:

Low pH (0.0 or close) corresponds to strong acidsHIgh pH (14.0 or close) corresponds to strong basesAcids have pH between 0.0 and 7.0Bases have pH between 7.0 and 14.0

Ithink it’s 3 as the answer.

The answer to the question is d
