Please answer all parts!!
Water ionizes by the equation H_2O(l) 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 constants, the value of K_w changes with temperature. What is the H^+ concentration for an aqueous solution with pOH = 4.25 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. The correct ranking cannot be determined. At a certain temperature, the pH of a neutral solution is 7.63. What is the value of K_w at that temperature? Express your answer numerically using two significant figures.
