WebJan 31, 2024 · All acids of the generic formula HA have pKa. HA − ⇀ ↽ − H + + A −. The equilibrium constant for this simplified reaction can be written as. Keq = [H +][A −] HA Ka = [HA]Keq = [H +][A −] pKa = − logKa. The pK a becomes a simple measure of the strength of an acid. The stronger the acid, the larger the K a and the smaller the pK a. cumberland county crown event center

WebAgora, vamos pensar sobre a reação inversa. O íon acetato irá funcionar com uma base, pegando esse próton da água e deixando estes elétrons para trás. Isso nos daria de volta o ácido acético e o hidróxido. Para a reação inversa, o ânion de acetato está funcionando como uma base. E a água está funcionando como um ácido. WebAug 29, 2014 · Using the properties of logarithms, Equation 2.2.8 can be rewritten as. 10 − pKw = 10 − 14. The equation also shows that each increasing unit on the scale decreases by the factor of ten on the concentration of H +. Combining Equations 2.2.4 - 2.2.6 and 2.2.8 results in this important relationship: pKw = pH + pOH = 14.

WebMar 13, 2024 · Working with such numbers is inconvenient, so to makes things easier, chemists have defined the pKa number as: pKa = -log Ka. According to this definition, the pKa value for hydrochloric acid is -log 10 7 = -7, while the pKa for ascorbic acid is -log (1.6 x 10 -12) = 11.80. As is evident, the smaller the pKa number, the stronger the acid.
