When the concentration of hydronium ions equals the concentration of hydroxide ions, it is called the

When the concentration of H₃O⁺ becomes equal to the concentration of OH⁻ ions, it is called the Neutral Solution.

Example:
              A neutral water with pH 7 contains Hydronium and Hydroxyl ions in following number,

                      [H₃O⁺]  =  1.0 × 10⁻⁷ M

                      [OH⁻]   =  1.0 × 10⁻⁷ M

Idon't see the pic?

Sorry i dont understand the question can you rephase it?
