Question

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 a naturally occurring buffer solution whose pH is maintained by  concentrations.

Step 1 — Evaluate Statement I:
A buffer solution is NOT just any mixture of salt and acid/base. It requires:
- A weak acid and its conjugate base (salt), OR
- A weak base and its conjugate acid (salt)
- Mixed in specific proportions (not "any" quantities)

If equal moles of strong acid and its salt are mixed, it's not a buffer. The statement says "any particular quantities" which is misleading — it must be specific ratios.
Statement I is FALSE ✗ (too broad/incorrect)
