The little 'p' means -log10 (that's the negative log to base 10).
Thus pH means -log10(Hydrogen ion concentration)
→ pH of the solution = -log10(7.0 x 10-2) ≈ 1.15
Yes, the pH of a solution is a measure of the concentration of hydrogen ions (H+) in the solution. pH is defined as the negative logarithm of the hydrogen ion concentration.
If you think to pH it is 7.
I do not understand what you are asking? Can you rephrase your question, please?
pH = -log [H+], so if the [H+] is 2.310 M, the pH = -0.3636
The pH of a solution is calculated using the formula pH = -log[H+]. Plugging in the given value of [H+] = 7.0x10^-7, you would get a pH of 6.15 for this solution.
Decreasing the concentration of H+ ions will raise the pH of the solution because pH is a measure of the hydrogen ion concentration. As H+ ions decrease, the solution becomes more basic and the pH value increases.
A solution with a pH of 4 has 10 times more H+ ions than a solution with a pH of 5. This is because the pH scale is logarithmic, with each whole number representing a tenfold difference in H+ ion concentration.

The pH of a solution with [H+] = 7.0 x 10^-2 is pH = -log(7.0 x 10^-2) = 1.15.
In a neutral solution, the H plus is equal to OH-. The pH level in such a solution is usually at 7.
apexvs answer 3.3
The pH of a neutral solution with equal concentrations of H+ and OH- ions is 7. This is because the concentration of H+ ions equals the concentration of OH- ions in a neutral solution, resulting in a pH of 7.
