Document Summary
Acids and bases occupy a very important place in the study of chemistry. Industrial processes that take place in aqueous solution and all life processes, which also take place in aqueous solution, depend on maintaining close control of the concentrations of acids and bases in solution. Acids are substances that produce h+ ions in aqueous solution and bases are substances that produce oh- ions in aqueous solution. The following relationship exists between the concentrations of h+ and oh- in all aqueous solutions (the brackets represent concentrations in molarity units): This relationship shows that as the concentration of h+ increases in a solution, the concentration of oh- must decrease, since the product of the two concentrations must be 1. 0 x 10-14. Neutral solutions are aqueous solutions that are neither acidic nor basic, meaning that the concentrations of h+ and oh- must be equal to one another.
