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. WebKa from pH We can use pH to determine the Ka value. pH is a standard used to measure the hydrogen ion concentration. pH = – log [H + ] We can rewrite it as, [H +] = 10 -pH. If …
