I Review Constants | Periodic Tabl
Water ionizes by the equation
H20(1) = H*(aq) + OH (aq)
• Part A
The extent of the reaction is small in pure water and dilute aqueous solutions. This reaction creates the following
relationship between (H'] and (OH ):
What is the H concentration for an aqueous solution with pOH = 4.00 at 25 °C?
K, = [H'||OH-
Express your answer to two significant figures and include the appropriate units.
Keep in mind that, like all equilibrium constants, the value of K, changes with temperature.
