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 pH is maintained by $H_2CO_3/HCO_3^-$ concentrations.
In the light of the above statements, choose the correct answer from the options given below.
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 pH is maintained by $H_2CO_3/HCO_3^-$ concentrations.
In the light of the above statements, choose the correct answer from the options given below.
- Statement I is false but Statement II is true
- Both Statement I and Statement II is true
- Both Statement I and Statement II is false
- Statement I is true but Statement II is false
The Correct Option is A
Solution and Explanation
Statement I: False. A buffer solution is a mixture of a weak acid and its conjugate base (or a weak base and its conjugate acid) in specific ratios. The statement's claim of "any particular quantities" is incorrect.
Statement II: True. Blood is a naturally occurring buffer system, primarily maintained by the H$_2$CO$_3$/HCO$_3^-$ system, which helps regulate pH within a narrow range.
Thus, only Statement II is correct.

- Let \( \vec{a} = \hat{i} + 2\hat{j} + \hat{k} \) and \( \vec{b} = 2\hat{i} + 7\hat{j} + 3\hat{k} \). Let \( L_1 : \vec{r} = (-\hat{i} + 2\hat{j} + \hat{k}) + \lambda \vec{a}, \lambda \in {R} \) and \( L_2 : \vec{r} = (\hat{j} + \hat{k}) + \mu \vec{b}, \mu \in \mathbb{R} \) be two lines. If the line \( L_3 \) passes through the point of intersection of \( L_1 \) and \( L_2 \), and is parallel to \( \vec{a} + \vec{b} \), then \( L_3 \) passes through the point:
