The pH of the given statement = 7.50
The pH of water determines how acidic or basic it is. The scale runs from 0 to 14, with 7 being neutral. pHs less than 7 indicate acidity, while pHs greater than 7 indicate base. pH is a measure of the relative amount of free hydrogen and hydroxyl ions in water.
At 25°C, the ion-product of water is equal to [H₃O⁺ ][ OH⁻] = 1.00 x 10^-10.
As we can see in the image:
The total number of spherical molecules is 22, as shown in the figure, and the number of green-colored molecules is ten times that of purple-colored molecules. This implies that the concentration of hydroxide ions is ten times that of hydronium ions.
[ OH⁻] = 10 [H₃O⁺ ]
If this is the case, the concentration of hydronium and the pH of the solution must be adjusted.
10 [H₃O⁺ ]² = 1.00 x 10^-10
[H₃O⁺ ]² = 3.86 x 10^-8
pH = -log[H₃O⁺]
= -log[3.86 x 10^-8]
= 7.50
The pH of the given statement = 7.50
