What is the ph of a solution with [h3o+] = 7.5 x 10-9 m?

pH = 8.125

Explanation:

The pH of a solution can be defined as measure or the quantity of hydrogen ion that is present in a solution. The pH of a solution determines how acidic or basic a solution is.

In order to be able to determine the pH of a solution, the molar concentration of the Hydronium ion  [H3O+] in the solution must be known.

The pH is then calculated using the formula :

pH = - log [H3O+].

[H3O+] = 7.5 x 10⁻⁹ M

pH = - log[7.5 x 10⁻⁹M]

pH = 8.125

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
