The hydrogen ion concentration is 1 × 10-7. What is the ph of this solution?
Naya [18.7K]

Answer:

  • <em>The pH of the solution is </em><u><em>7</em></u>

Explanation:

<em>The pH</em> 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⁺]

<em>The hydrogen ion concentration of this solution is 1 × 10⁻⁷ M.</em>

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 acids
  • HIgh pH (14.0 or close) corresponds to strong bases
  • Acids have pH between 0.0 and 7.0
  • Bases have pH between 7.0 and 14.0
