What is the [H+] of a solution with a pH of 5.0? Use a scientific calculator as needed. 7.7\cdot10^{-5} 2.5\cdot10^{-6} 1.0\cdot10^{-5}

The pH of a solution is a measure of the hydrogen ion concentration, [H+]. The pH is calculated as the negative logarithm (base 10) of the [H+] in moles per liter.

So, if we have a solution with a pH of 5.0, we can calculate the [H+] as follows:

1. Write down the pH value: pH = 5.0
2. Use the definition of pH, which is pH = -log[H+]. We need to solve this equation for [H+], which gives us [H+] = 10^-pH.
3. Substitute the given pH value into the equation: [H+] = 10^-5.0
4. Using a scientific calculator, calculate the value of 10^-5.0.

The result is [H+] = 1.0 x 10^-5 M. So, the [H+] of a solution with a pH of 5.0 is 1.0 x 10^-5 M.
