WebThe relationship between Ka and Kb for any conjugate acid-base pairs is as follows: (Ka)(Kb) = Kw Where Kais the ionization constant of the acid form of the pair, Kbis the ionization constant for the base form of the pair, and Kwis the ionization constant for water. This equation is used to find either Kaor Kb when the other is known. WebPlug those values into the equation for Kb: Kb = [OH¯] • [CH₃OOH] / [CH₃OO¯] ... Well, we had 50 mL of a 0.200 molar solution of acetic acid. So, the concentration of acetic acid, the concentration of acetic acid was equal to 0.200 M, and that's equal to moles over liters. So, 50.0 mL would be 0.0500 liters. So this would be 0.0500 liters.

WebRead these instructions to learn how to use this acids and bases chart. The table lists the K a values and the strength of each acid and base. Strong acids are listed at the top left-hand corner of the table and have Ka values >1; Acids with a K a value less than one are considered weak and get weaker as we move to the bottom of the table. WebThe Ka values of most weak acids range from 10 -2 to 10 -14. The same information is provided by pKa, but in a different format. The stronger the acid, the lower the pKa value. Alternatively, the weaker the acid, the higher the pKa value. The pKa value of weak acids is usually between 2 and 14. Converting From pKa to Ka
