Ka to pKa - How to Convert Ka to pKa, Fo…

WebA pH (little p) of 7 only means neutral water at 25°C, but for other temperatures this means a pH above or below 7. This is due to the changing value of water's self-ionization constant, Kw, with temperature. At 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). Web• The lesser the value of Ka, the weaker the acid. • Similar to pH, the value of Ka can also be represented as pKa. ... • Calculate the ratio of CB to WA, if pH is given • Calculate the pH, if ratio of CB to WA is known • Calculate the pH of a weak acid solution of known concentration • Determine the pKa of a WA-CB pair WebpH is equal to the sum of the pKa value and the log of the conjugate base concentration divided by the weak acid concentration. Half through the equivalence point: pH = pKa It’s worth mentioning that this equation is occasionally written for the Ka value instead of the pKa value, so it is familiar with the relationship. pKa = – logKa how many presidents are there been
