In a 0.2000M solution of a monoprotic weak acid (HA), [H*] = 9.86 X 104 M. What is the dissociation constant (K₂) of this acid? The equilibrium constant of [H*] and of the corresponding anion are both equal to 9.86 X 104 M What is the equilibrium concentration of the acid [HA] to four significant figures? Type your answer here. (The equilibrium value of [HA] is the initial value minus the equilibrium value of [H*].) The formula for the dissociation constant is K₂ = ([H*] X [A]) + [HA] Substitute the known values and calculate. Give your answer in scientific notation and to three significant digits. Ka = Type your answer here. X 10-6
