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. WebStudy with Quizlet and memorize flashcards containing terms like Will an acidic drug with a pKa of 7.1 be more or less than 50% ionized a physiologic pH?, 2.

WebUsually, these .pka files contain information regarding the practice session saved using the .pka extension. The file extension is also used by the PKarc compression utility and these files are deemed as PKArc compressed file archive because the whole archive containing the compressed files use the .pka file extension. WebThe pKa is defined as the negative log of the Ka. If we wanted to find the pKa for methanol, all we have to do is take the Ka and take the negative log of it. So the pKa is equal to the negative log of 2.9 times 10 to the negative 16. Let's get out the calculator and let's do that. Negative log of 2.9 times 10 to the negative 16. WebMar 14, 2024 · Ka = 10 (-pKa) When pKa is a whole number, such as -7, this operation is easy to perform, but when it contains a fraction, such as 7.5, you may have to look up the value in a table. You can also find it on a scientific calculator by inputting the number and pressing the exponent key, which either looks like a hat (^) or is denoted by 10 x. tthf
