Web16 mrt. 2024 · Here are the steps to calculate the pH of a solution: Let's assume that the concentration of hydrogen ions is equal to 0.0001 mol/L. Calculate pH by using the pH to H⁺ formula: \qquad \small\rm pH = -log (0.0001) = 4 pH = −log(0.0001) = 4 Now, you can also easily determine pOH and a concentration of hydroxide ions using the formulas: WebThe pH electrode is full of ions, both in the filling solution and in the hydrated portion of the pH sensing glass. So when an electrode is submerged in a solution that has no ions, the ions in the electrode will want to move out into the solution in …
