Water ionizes by the equation H_2 O(l) rightarrowoverleftarrow H^+ (aq) + OH^- (aq) The extent of the reaction is small in pure water and dilute aqueous solutions. This reaction creates the following relationship between [H^+] and [OH^-]; K_w = [H^+] [OH^-] Keep in mind that, like all equilibrium constant, the value of K_w changes with temperature. What is the H^+ concentration for an aqueous solution with pOH = 4.31 at 25 degree C? Express your answer to two significant figures and include the appropriate units. Arrange the following aqueous solutions, all at 25 degree C. in order of decreasing acidity. Rank from most acidic to most basic. To rank items as equivalent, overlap them.
