Buffering range vs buffering capacity
WebBuffer capacity Buffer capacity is a quantitative measure of the resistance to change of pH of a solution containing a buffering agent with respect to a change of acid or alkali … WebThe buffer range is the pH range over which a buffer acts effectively. Buffer capacity - the number of moles of acid or base that must be added to one liter of the buffer solution in order to lower or raise the pH by one unit. The more similar the concentration of the two components, the greater the buffer capacity.
