Given below are two statements: Statement \((I)\) : \(A\) Buffer solution is the mixture of a salt and an acid or a base mixed in any particular quantities. Statement \((II)\) : Blood is naturally occurring buffer solution whose \(\mathrm{pH}\) is maintained by \(\mathrm{H}_2 \mathrm{CO}_3 / \mathrm{HCO}_3\) concentrations. In the light of the above statements, choose the correct answer from the options given below.
- A Statement \(I\) is false but Statement \(II\) is true
- B Both Statement \(I\) and Statement \(II\) is true
- C Both Statement \(I\) and Statement \(II\) is false
- D Statement \(I\) is true but Statement \(II\) is false
Answer & Solution
Correct Answer
(A) Statement \(I\) is false but Statement \(II\) is true
Step-by-step Solution
Detailed explanation
Buffer solution is a mixture of either weak acid / weak base and its respective conjugate. Blood is a buffer solution of carbonic acid \(\mathrm{H}_2 \mathrm{CO}_3\) and bicarbonate \(\mathrm{HCO}_3^{-}\) Statement \(1\) is false but Statement \(II\) is true.
