Question

Quizplus · Accepted Answer

Chemical buffer systems do not promote H⁺ excretion by the kidneys when acidosis is present. This is the function of the renal system in the body. Chemical buffer systems work within a fraction of a second to buffer changes in pH by either accepting or donating hydrogen ions, depending on the pH of the solution. The direction of their reaction is determined according to the law of mass action, which states that the reactions proceed in the direction of the lower concentration of reactants.
