math is the study of numbers, shapes, and patterns. For those who struggle with math, equations can seem like an impossible task. Solution: We are given the pK_a for butyric acid and asked to calculate the K_b and the pK_b for its conjugate base, the butyrate ion. Understanding Ka and pKa Ka = [H+][A-]/ [HA] pKa = - log Ka at half the equivalence point, pH = pKa = -log Ka. Then use the fact that the ratio of [A ] to [HA} = 1/10 = 0.1 pH = 4.75 + log 10 (0.1) = 4.75 + (1) = 3.75 This means that at pH lower than acetic acid's pKa, less than half will be dissociated, or ionized; at higher pH values, more than half will be ionized. A Simple Method That Shows You How to Convert pKa to Ka Easily Acid Base pH and pKa Calculations in MCAT Chemistry - Leah4sci You do need to pay to get worked out solutions but in a pinch it can at least speed up getting your desired answers, sometimes you have to pay to see the steps and explanation, but for the most part it's free. If you don't take the negative log and instead take the positive log, then you'll be working with negative numbers constantly. Our goal is to make science relevant and fun for everyone. The accurate result for PKa is 9.25. Thus Ka = 10-pKa. The pKa to pH converter calculator is an online tool that can find the pH of a liquid solution using the pKa value and concentration.
