Kw Chemistry

Introduction to the water ionization constant Kw Pure water undergoes auto-ionization or self-ionization by donating or accepting a proton between two molecules of water to form H3O+ and OH– ions. This is also known as autoprotolysis or amphoteric nature of water. The hydronium ion is a very strong acid and hydroxide ion is a very … Read more

Equilibrium Constant Kp

Equilibrium Constant Kp Definition When a reaction is at equilibrium, the forward and reverse reaction rate are same. The concentration of the reactants and products stay constant at equilibrium, even though the forward and backward reactions are still occurring. When one or more of the reactants or products are gas in any equilibrium reaction, the … Read more

Le Chatelier’s Principle

Le Chatelier’s Principle Definition Le Chatlier’s principle is also known as “Chatelier’s principle” or “The Equilibrium Law”. Le Chatelier’s principle states that if a dynamic equilibrium is disturbed by changing the conditions (such as concentration, temperature and pressure changes) , the position of equilibrium shifts to counteract the change to reestablish an equilibrium.┬áIf a chemical … Read more
