Ph from oh- concentration
Did you know?
WebThe pH scale is used to rank solutions in terms of how acidic or how basic they are. It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution.

Web30. jún 2016 · 0 There was this exercise which asked to find the OH- concentration given the H+ concentration, i firstly calculated the pH as -log [H+], did 14-pH to find the pOH and then did 10^ (-pOH) to find the concentration of OH-. My textbook used the fact that Kw (water equilibrium constant) is essentially Kw = [OH-] * [H+] so it did [OH-] = Kw/ [H+] WebTherefore, if the concentration of \text {H}^+ H+ decreases by a single factor of 10 10, then the \text {pH} pH will increase by 1 1 unit.
