Buffer solutions are those whose pH is almost constant due to the presence of mechanisms to control its fluctuation. This is due to the presence of excess of either excess of H+ or OH- etc. so that there is no effect when some of either of them may enter from outside. Eg. blood in human body is at constant pH of about 7.4. It uses H+ and HCO3- ions to regulate any change in it's pH (like during respiration)
