Calculate from simple stoichiometry amount of HCl in the gastric juice, then its concentration - once you know concentration of HCl pH calculation … WebSince hydrochloric acid is monoprotic, the concentration of the solution is equal to the concentration of protons. Using this value and the pH equation, we can calculate the pH. Now we can find the pOH. The sum of the pH and the pOH is always 14. The pOH of the solution is 7.8. Alternatively, a shortcut can be used to estimate the pH.

So we would just need to plug in the pOH into this equation … WebpOH from Molarity. We can use molarity to determine the pOH value. pOH is equivalent to the negative log of hydroxide ion (OH –) concentration. pOH = – log [OH –] By putting the value of the concentration of OH – ion, we can determine the value of pOH. Example: Calculate the pOH value of an aqueous solution whose molarity is 6.3 × 10-5 M. crowther lodge motor company ltd
