What is H+ concentration from pH?
In this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation pH = − log [H+] we can solve for [H+] as … by exponentiating both sides with base 10 to “undo” the common logarithm. The hydrogen ion concentration of “Solution A” is [H+] = 10−5.6 ≈ 0.0000025 = 2.51 × 10−6 M.
Is pH the concentration of hydrogen ions?
Hydrogen ion concentration is more conveniently expressed as pH which is the logarithm of the reciprocal of the hydrogen ion concentration in gram moles per liter. Thus in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−) concentrations are equal and each is equal to 10−7. A pH of 7 is neutral.
The overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale (Figure 1). Therefore the more hydrogen ions present the lower the pH conversely the fewer hydrogen ions the higher the pH. … It is neither acidic nor basic and has a pH of 7.0.

Does pH Measure H+?
As a result pH is a measure of hydrogen ion activity. The activity coefficient is a function of the ion concentration and approaches 1 as the solution becomes increasingly dilute. Therefore hydrogen ion concentration and hydrogen ion activity are nearly equal in very dilute samples.

Definition of hydrogen-ion concentration
: the concentration of hydrogen ions in a solution expressed usually in moles per liter or in pH units and used as a measure of the acidity of the solution indicator dyes for narrow ranges of hydrogen-ion concentration.
What is the hydrogen ion concentration of a solution of pH 4?
10-4mol/l
This means for example that a hydrogen-ion concentration of a solution with a pH of 4 is 10-4mol/l meaning it contains 0.0001 mol of hydrogen ions in a solution of 1 liter.
