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 HCO3-, H+ ions and CO2 concentration.

Choose the correct option.

  • Statement I is correct but II is incorrect

  • Statement II is correct but I is incorrect

  • Both statement are correct

  • Both statement are incorrect

Solution

B.

Statement II is correct but I is incorrect

Statement II is correct and statement I is incorrect. It can be corrected as the production and removal of CO2+ and H+ together with the use and transport of O2 that cause chemical changes in the blood.

Buffers in the blood protect against large changes in blood pH.
