How would the addition of a few drops of a NaOH solution affect the equilibrium in system (B)? HC2H3O2(ag)=H+(ag) + C2H3O2- (ag) O No effect will be observed. The hydroxide would neutralize the H+ ions present and shift the equilibrium to the left. O The hydroxide would neutralize the H+ ions present and shift the equilibrium to the right.
Use the References to access important values if needed for this question. In an aqueous solution of a weak acid, HA, the assumption is often made that [HA]equilibrium = [HA]nitial: This approximation is reasonable if the initial concentration of the acid is sufficiently large compared to Ka. What multiple of K, must the initial concentration of a weak acid exceed, for the initial concentration and the equilibrium concentration to be within 9.98 percent of each other?
A saturated solution of a certain acid (0.1 M concentration) dissociates into cation [H+] and anion [A−], where [H+] = [A−]. When this solution dissociates, the following equilibrium equation is established. [H+][A−] [HA] = 1.000 ✕ 10−8. Find [H+] (in M). (Hint: If [H+] = x, then [HA] = 0.1 − x. Give your answer in scientific notation, correct to three decimal places.)
