The dissociation constant of the weak acid HF IS Ka+ [H+][F-]/[HF]. If at equilibrium the concentrations of H+ and F- are each 2.6 X 10-3M and the concentration of HF is 0.010 M, what is Ka for HF?
The reaction between HCO-3 and its conjugate acid creates a very imortant buffer in your blood. Explain what a buffer does.
