Find the Ph of solutions with the concentrations

1.15 x 10^-6M

You need to specify what the solute is

And it's pH and not Ph. They mean something entirely different.

To find the pH of a solution with a concentration of 1.15 x 10^-6 M, you need to use the formula for pH. The pH of a solution is determined by the concentration of hydrogen ions (H+) in the solution.

The pH scale ranges from 0 to 14, where a pH of 0-6 is acidic, a pH of 7 is neutral, and a pH of 8-14 is basic or alkaline.

To find the pH, you need to take the negative logarithm (base 10) of the hydrogen ion concentration:

pH = -log[H+]

Given the concentration of 1.15 x 10^-6 M, you can substitute it into the equation:

pH = -log(1.15 x 10^-6)

Using a scientific calculator, calculate the logarithm of the concentration:

log(1.15 x 10^-6) ≈ -6.939

Finally, take the negative of this value to find the pH:

pH ≈ -(-6.939) ≈ 6.939

Therefore, the pH of a solution with a concentration of 1.15 x 10^-6 M is approximately 6.939.
