Respuesta :

pH = - log [ H⁺ ]

pH = - log ( 10⁻⁷ )

pH = 7 

hope this helps! 
The pH of the solution may be solved by the equation,
                                     pH = -log[C]
Substituting the given concentration of the hydrogen ion in the equation,
                                      pH = -log[10^-7] = 7
Thus, the pH of the solution is 7 which means that it is neither basic nor acidic.
