Pka alkoholi
WebMay 1, 2015 · Water has a pKa of 15.7 while methanol has a pKa of 16. When you look at the conjugate base of methanol the one carbon group is pushing its electrons towards the oxygen making the oxygen slightly … 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.
