Web23 Sep 2024 · How do you calculate the pH of calcium hydroxide? Calcium hydroxide in water at 25 °C. 2. Calcium hydroxide in a buffered solution with a pH = 13.00 + Y where Y = the last two digits of your Student ID Number divided by 100. (If your Student ID Number is 100123456, then the pH = 13.56.) WebThe pH of bases in aqueous solution ranges from greater than 7 (the pH of pure water) to 14 (though some bases have pH values greater than 14). The formula for pH is: pH = -log 10 [H +] Sometimes, however, it is more convenient to focus on the pOH of bases, rather than the pH. The pOH more directly references the [OH-]. pOH = -log 10 [OH-] dr casanova 81
