So to ease that, pKa came into existence. This video teaches you how to tackle anti-log questions as they arise on your MCAT, without the use of a calculator. Since a logarithm in general corresponds to the power of 10, M will be the most important number for calculating the magnitude of the pKa value. Quick ka to kb conversion, pOH WITHOUT an ICE TABLE, and convert from pOH to pH. To convert Ka into pKa, get out your calculator and find -log, then open bracket, Ka value, close bracket. It is used to measure the acid strength. without app I would have to work 5-6 hours tryna find the answer and show work but when I use this I finish my homework in 30 minutes or so, the camera caption has improved overtime . For those who struggle with math, equations can seem like an impossible task. This is especially useful in Chemistry questions asking you to solve H+, OH-, or general ion concentrations, not to mention ka and kb values This video teaches you how to solve the potentially impossible MCAT logarithm questions without a calculator by showing you what to look for and numbers to recognize for simple and fast conversions.

The value of Ka will be = 1.778 x 10^-5. {\displaystyle Ka=10^{-pKa}} for this conversion. Accessibility StatementFor more information contact us atinfo@libretexts.orgor check out our status page at https://status.libretexts.org. By raising 10 to the power of -pKa, we can calculate the acid dissociation constant. pH of acid by 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. A large \(K_a\) value indicates a stronger acid (more of the acid dissociates) and small \(K_a\) value indicates a weaker acid (less of the acid dissociates). pKa=. How do you convert pKa to Ka? | Socratic When we write log_ab = c, we specify that a^c =b. Harold Hammer. Alternatively, it can be used to find the pOH value of a base by inputting its pKb value in the "pKa=" input field. Purdue University: Brnsted Acids and Bases, Khan Academy Organic Chemistry: Ka and pKa Derivation. In the Bronsted-Lowry formulation of acids in solution, the acid donates a proton and the solution accepts one. For those who need fast solutions, we have the perfect solution for you. pKa is defined as the negative logarithm (-log) of Ka, which means you calculate pKa with the calculation . He is also a historian who holds a PhD from The University of Notre Dame and has taught at universities in and around Pittsburgh, PA.

Your estimate of Ka is 10.8, while the actual answer is 10.63. It can be used to calculate the concentration of hydrogen ions [H+] or hydronium ions [H3O+] in an aqueous solution. The mathematical operation you perform is Ka = antilog (-pKa).
