the lower the ka value, the higher the pka value, and the weaker the acid. predict equilibrium and strength of acids using ka and pka ka can be used to calculate the equilibrium position: when ka is big, the creation of dissociation products is encouraged. when ka is low, the un...
Calculator Chemistry book Pen Paper TL;DR (Too Long; Didn't Read) Online, or in a chemistry book, you can find a table of acid and base dissociation constants. References Purdue: Bronsted Acids and Bases pH Scale:pKa and Ka Cite This Article MLA Pesacreta, Mara. "How To Calculate Kb ...
1.25M NaOH means that in the solution there are Ma(2-) and HMa- only. Simple stoichiometry gives [HMa-] = 0.25 and [Ma(2-)] = 0.5 HH equation: pH = pKa2 + log([Ma(2-)]/[HMa-]) rearranging: pKa2 = pH + log([HMa-]/[Ma(2-)]) using calculator: pKa2 = 6.03 + log(0...
This pKa calculator helps you find the pKa from pH with the Henderson-Hasselbalch equation or with acid dissociation constant (Ka) values.
