A buffer solution is formed by a weak acid and its conjugate base or a weak base and its conjugate acid.

1. CH3CO2H with LiCH3CO2: This is a weak acid (acetic acid) and its conjugate base (acetate ion), so it will form a buffer solution.

2. H2PO4 with K2HPO4: This is a weak acid (dihydrogen phosphate) and its conjugate base (hydrogen phosphate), so it will form a buffer solution.

3. HNO3 with LiNO3: Nitric acid (HNO3) is a strong acid, not a weak acid, and its conjugate base is the nitrate ion (NO3-). Therefore, this pair will not form a buffer solution.

4. NH3 with NH4I: This is a weak base (ammonia) and its conjugate acid (ammonium ion), so it will form a buffer solution.

So, the pair that will not form a buffer solution is HNO3 with LiNO3.
