    Statements I Buffer is a compound that destabilises the pH of solution by removing or releasing hydrogen ions. Statement II Human blood has a buffer solution. Its pH is maintained by\[HCO_{3}^{-},{{H}^{+}}\] ions and\[C{{O}_{2}}\]concentration. Choose the correct option.

    A)  Statement I is correct but II is incorrect

    B)  Statement II is correct but I is incorrect

    C)  Both statement are correct

    D)  Both statement are incorrect

    Correct Answer: B

    Solution :

                    Statement II is correct but I is incorrect as the production and removal of\[CO_{2}^{+}\]and\[{{H}^{+}}\] together with the use and transport of\[{{O}_{2}}\]cause chemical changes in the blood. Buffers in the blood protect against large changes in blood pH.
