101. Chemical Sciences: Ionization Constants Of Acids And Bases The ionization constants of acids and bases other than water are dealt with ina similar way. The ionization of acetic acid in water is described by the http://www.ualberta.ca/~jplambec/che/p101/p01133.htm

Chemical Sciences Chemical Thermodynamics Chemical Equilibrium Acids and Bases: Ionization Constants of Acids and Bases Since it is known that hydronium ion will react with hydroxide ion to give water, the dissociation of water to hydronium ion and hydroxide ion must be reversible. Any reversible reaction is described by an equilibrium, and for the dissociation of water that equilibrium is 2H O + OH . The position of any equilibrium is given by an equilibrium constant, K , which for the dissociation of water according to the acid-base reaction just described is: K a (H O a (OH a (H O) In this equation, the chemical activities a can be approximated by the appropriate molar concentrations, indicated here by the use of square brackets in the form K = [H O ][OH ]/[H O] Since the concentration of water is approximately constant, it is normally included with the equilibrium constant of water (in other words, the chemical activity of water is taken as that of pure water, which is unity). In that case the equilibrium constant above is known as the ion product of water or the autoionization constant of water and indicated by the subscript w, so that by definition:

Acids by Ron Kurtus (revised 30 October 2004) Acids are chemical compounds that can react with metals and other substances to "eat them away" or damage them. You can usually identify an acid by its pH value, such characteristics as taste or feel, and its chemical formula. One common place acids are found is in soft drinks. Questions you may have are: What are the characteristics of acids? What type of a chemical formula does an acid have? What are acids used for? This lesson will answer those questions. There is a mini-quiz at the end to check your understanding. Note: If you want to hear the text being read, click the

While these definitions don't contradict each other, they do vary in how inclusive they are. Antoine Lavoisier, Humphry Davy, and Justus Liebig also made observations regarding acids and bases, but didn't formalize definitions. Svante Arrhenius acids produce H ions in aqueous solutions bases produce OH ions in aqueous solutions water required, so only allows for aqueous solutions only protic acids are allowed; required to produce hydrogen ions
