Unit 14 Acid Base Equilibria
"Your blood is a buffered solution. If it wasn't, your pH would go way down every time you had a soda and way up whenever you took some Tums. It's not a very handy survival technique to die every time you have a soda." ~ Mr. Guch

Reversible Reactions
062 - Reversible Rxns How reversible reactions achieve equilibrium as reactants are converted to products and products are converted to reactants. A model shows how forward reaction rates and reverse reactions rates approach equality at equilibrium. Physical, chemical, biological, and ecological examples of reversible reactions are included. The Reaction Quotient
063 - The Rxn Quotient How the reaction quotient is used to determine the progress of a reversible reaction. The reaction quotient (Q) is the ratio of the concentration of products to the concentration of reactants. The reaction quotient will equal the equilibrium constant when the reaction is at equilibrium. (7:08) |
