Buffering acids

WebThe buffering capacity of the acid-base pair is the ptC 1 pH unit. In biological fluids the phosphate and carbonate ions act as buffers. Amino acids, proteins, nucleic acids and … 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.
