The pH of the solution with a concentration of 7.6 × [tex]10^{-7}M[/tex] [tex]H_{3}O^{+}[/tex]will be 6.12.
The pH of water indicates how acidic or basic it is. The scale runs from 0 to 14, with 7 representing neutrality. Acidity is indicated by a pH less than 7, while a pH greater than 7 denotes a base. The relative number of free hydrogen, as well as hydroxyl ions in water, and hydroxyl ions in water is measured by pH .
It is known that ,[[tex]H_{3}O^{+}[/tex]]=[tex][H^{+} ][/tex]
pH can be calculated by the formula:
[tex]pH = -logH^{+}.[/tex]
Now, put the value of hydrogen ion in above equation
pH = -log[7.6×10^{-7}M]
= -log(7.6)-log(10^{-7}
= -0.88+7log 10
= -0.88 +7
= 6.12.
Therefore, the pH of the solution will be 6.12.
