Question
Part A
Water ionizes by the equation
=H+(aq) + OH (ag)
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 = 2.73 at 25 °C?
Express your answer to two significant figures and include the appropriate units.
Kw = [H*][OH¯]
