Homework Help: Grade 7 pH question.

  1. Nov 8, 2005 #1
    The tern "buffer" is used in many products. What is a buffer? Some weak acids and bases work as a buffer system. Biocarbonate (HCO3-) is a common ion in your blood stream which acts as a buffer. Write an equation for how the pH of blood is restored to normal range when it bocomes acidic using buffering agent.

    Isnt buffer a thing that neutrolizes the pH? I really need help...

    Actually a buffer solution (in chemistry) resists a change in pH.. Here is a reference that offers a useful explanation.
