The solution is classified as a buffer if the molarity ratio of the weak acid-base conjugate pair is adjusted close to 1:1. Based on Le Chatelier's principle, the equilibrium must significantly shift left, such that the percent dissociation of the acid b...
Is it possible for a solution to have a negative pH? What will happen to the pH of an acid solution if some of the water evaporates? What is the pH of a 0.1 M acid solution? How much does the pH change if 0.0012 M KNO_2 was added to 0.00067 M HNO_2? (Ka = 4.5e-...
A 0.05 M solution of a weak acid is 1% ionized. What is the approximate Ka of the acid?Percent Ionization:Percent ionization is a way to describe how much of the acid is dissociated relative to the initial concentration. The equation to calculate percent ionization i...
