Document Summary
Ratio of buffer component concentrations: acid or base concentration depends on this ratio since ka or kb values are constants. Used to find the ph value without finding hydronium concentration first. Used to prepare a buffer id known ph by mixing the appropriate amounts of conjugate base and the acid. Buffer capacity: measure of the strength of the buffer, showing how effective it is at maintaining the changed ph level after adding the appropriate acid or base. The greater the concentrations of buffer substance, the greater the solution"s resultant power to resist changes in ph. The more equal the buffer component concentration is to the original acid/base, the greater the buffer capacity ( the greater the solution"s ability to resist change. ***basically the more product you put in, the better it keeps toward the reactants*** Buffer range: the buffer is effective only within the determined ph range.
