WebAug 24, 2024 · pOH is 12.3. Explanation: let's first get the pH of nitric acid: but: [H†] = 0.020 M. therefore: but, pOH = 14 - pH WebJun 15, 2024 · pOH = -log[OH – ] pOH = -log(0.25) pOH = 0.60. Think about the answer and whether it makes sense. This is a strong base solution, so you expect it has a high pH …
pH and pOH Chemistry for Majors - Lumen Learning
WebAt 25°C we know it to be 1.0 x 10^(-14), but at something like 50°C it's about 5.5 x 10^(-14). When we do the math using the Kw at 50°C to find the pH and pOH we find that they are both lower than 7, simply meaning that there more hydronium and hydroxide ions in neutral water at higher temperatures. Hope that helps.
