Initial concentration of a weak acid exceed

Assignment Help Chemistry
Reference no: EM131895404

In an aqueous solution of a weak acid, HA, the assumption is often made that [HA]equilibrium = [HA]initial. This approximation is reasonable if the initial concentration of the acid is sufficiently large compared to Ka. 

What multiple of Ka must the initial concentration of a weak acid exceed, for the initial concentration and the equilibrium concentration to be within 9.40 percent of each other?
