WebThe pH Scale provides a range of acidic, neutral and basic solutions between 0-14. The pH scale is directly related to the OH- concentration while inversely related to the H+ concentration. A pH value increases as the OH- ion concentration increases, while the H+ ion concentration decreases with the increasing pH value. WebTo calculate the pH, you use the formula -log {H+} = pH So, -log (.0001) = 4 This means the pH of the solution is 4 This calculation is the same for pOH, If the [OH-] value is .0001, than using the -log equation, you can figure out the pOH is 4 Now, lets say you have the pH value, you use this equation to find the [H+] 10^ (-pH)
