Disagree with the student’s claim From part (b) above, pK a for propanoic acid is log(1.3 10 5) = 4.89.Because 4.83 is so close to a 4.89, the pH at the equivalence point in the titration First, let's talk about the basic concepts of stoichiometry. First of all, we have to start with a balanced reaction. Let's say that we have this equation, which is the combustion of methane. CH_4 + O_2 \rightarrow CO_2 + H_2O C H 4 +O2 → C O2 +H 2O. Now, this equation is not yet balanced.
