A certain weak acid has a dissocation constant of1.0×10−4. The equilibrium constant for its reaction with a strong base is View Solution A certain weak acid has a dissociation constant1.0×10−4. The equilibrium constant for its reaction with a strong base is : ...
HF <--> 1/2 H2+ 1/2 F2 Ka = [H]1/2[F]1/2/ HF I assumed it was at equilibrium, so therefore H = F because of a 1:1 molar ratio ((.00489)1/2(.00489)1/2) / 7.2 X 10 -4 = [HF] I got 7.2 X 10 -2 as my answer...what am I doing wrong?
The dissociation of weak electrolyte (a weak base or weak acid) is expressed in terms of Ostwald's dilution law. An acid is substance which furnishes a proton or accepts an electron pair, where a base is proton acceptor or electron pair donor. Stronger is acid, weaker is its conjugate bas...

The base dissociation constant, Kb, for the reaction is analogous to the acid dissociation constant, Ka. A−+H2O⇌HA+OH−Kb=KeqH2O=HAOH−A− Again by analogy with the strengths of weak acids, the strengths of weak bases, Kb, are conveniently expressed as pKb values, where pKb ...
Ka chemistry - An acid dissociation constant (Ka) is a quantitative measure of the strength of an acid in solution. An acid dissociation constant, Ka is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a c
of a 0.0900 M solution of a weak acid HA with Ka = 1.00 x 10-5. If the H3O+ of a solution is 3.8 x 10-12 M, what is the pH of the solution? What is the acid dissociation constant for HA if pH = 2.74? Calculate the pH of a 0.10 M weak acid, HA, whos...
