What is the H+concentration for an aqueous solution with pOH=4.09 at 25C ? Water ionizes by the equation H2O(l)H+(aq)+OH(aq) Express your answer to two significant figures and include the appropriate units. The extent of the reaction is small in pure water and dilute aqueous solutions. This reaction creates the following relationship between [H+]and [OH]: Kw=[H+][OH] Keep in mind that, like all equilibrium constants, the value of Kw changes with temperature. Part B Arrange the following aqueous solutions, all at 25C, in order of decreasing acidity. Rank from most acidic to most basic. To rank items as equivalent, overlap them. Arrange the following aqueous solutions, all at 25C, in order of decreasing acidity. Rank from most acidic to most basic. To rank items as equivalent, overlap them. At a certain temperature, the pH of a neutral solution is 7.35 . What is the value of Kw at that temperature? Express your answer numerically using two significant figures
