WebDoing the math, we find that the pK a of acetic acid is 4.8. The use of pK a values allows us to express the acidity of common compounds and functional groups on a numerical scale of about –10 (very strong acid) to 50 (not acidic at all). Table 5.2. 1 at the end of the text lists exact or approximate pK a values for different types of protons ... WebThe greater the value of K a, the more favored the H + formation, which makes the solution more acidic; therefore, a high K a value indicates a lower pH for a solution. The K a of weak acids varies between 1.8×10 −16 and 55.5. Acids with a K a less than 1.8×10 −16 are weaker acids than water. If acids are polyprotic, each proton will have ...
