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 \(\mathrm{H}_2 \mathrm{CO}_3 / \mathrm{HCO}_3^- \Theta\) concentrations.
In the light of the above statements, choose the correct answer from the options given below :
Statement I is true but Statement II is false
Both Statement I and Statement II are true
Statement I is false but Statement II is true
Both Statement I and Statement II are false
Solution
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.
