Acid-Base Calculations The Ion-Product Constant for Water‚ Kw Water undergoes ionization to a small extent: H20(l) H+(aq) + OH–(aq) The equilibrium constant for the reaction is the ion-product constant for water Kw: (1) This is a key equation in acid-base chemistry. Note that the product of [H+] and [OH–] is a constant at a given temperature (Eq(1) value is for 25oC). Thus as the hydrogen ion concentration of a solution increases‚ the hydroxide ion concentration decreases

Many people would rather make money now rather than later. Laurence Shatkin wrote a blog post called “Education Pays‚ but Perhaps Less Than You Thought” in which he brings up why the U.S. Bureau of Labor Statistics fails to mention the whole story when comparing numbers to those with a higher education and those without one.
