It is used in everyday life, from counting to measuring to more complex calculations. Find pH. Step 3: Solve for Ka K a or pKa p K a. You solve this by raising both sides of the original relationship to powers of 10 to get: 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. http://leah4sci.com/MCAT Presents: MCAT Math Without A Calculator Video 9 - Solving MCAT antilog calculations without a calculatorWatch Next: Logarithms an. Work on the task that is enjoyable to you. To create a more manageable number, chemists define the pKa value as the negative logarithm of the Ka value: pKa = -log Ka. This article has been viewed 2,824 times. 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). This formula is based on the definition of pKa which is the negative logarithm of the acid dissociation constant. pKa is expressed as a common logarithm (base 10) and not as a natural logarithm (base e). Converting to the -log means that a lower pKa value indicates a stronger acid, as opposed to the Ka, in which a higher Ka value indicates a stronger acid. var tr_would_you_like_to_opt_out = "Would you like to opt out from selling your personal informaion for the purpose of ads personalization?
