WebAug 7, 2011 · You can easily get the pH of the solution at this point via the HH equation, pH=pKa+log [A-]/ [HA]. Since [A-]= [HA] at the half-eq point, the pH is equal to the pKa of your acid. If you look at a titration curve, your half-eq point is the flattest part of the cure while the equivalence point is at the steepest part. WebNov 21, 2014 · Using the standard concentration c ∘ we do not have to care about units. pH = − lg(c(HX +) c ∘) Now we can substitute in (4) and we will have a nice definition of the pH of a neutral solution. pH = − lg(√Kw c ∘) The second formulation includes a very crucial point. orange tube fungus https://p4pclothingdc.com
