Question

Q. H+ does not exist freely. Explain?​

Answer 1

Answer:

• $\rm H^+$(proton) is formed by loss of electron from hydrogen atom.

• The nucleus of proton is of extremely small size (-1.5 x 10-³ pm) compared to normal atomic and ionic sizes (50 to 200 pm).

• Consequently, $\rm H^+$does not exist freely and is always associated with other atoms or molecules.

Answer 2

Answer:

hope it is clear to you please mark as brilliant answer

Explanation:

H+ cannot exist in free state practically cause, in a solution in which water or any polar solvent is used, the H+ ion is hydrolyzed to form H3O+ ion, hydration energy is higher for H3O+ so it's more stable, also protonation of ions results in formation of more stable bronsted Lowry acid bases. Also zundel cation H502+, eigen cation H9O4+ play an important role in proton diffusion

The above case of H+ is just due to the self ionization of water, there are many examples which show this phenomenon based on bronsted Lowry acid bases theory of strong and weak acids, solvation and hydration energies and also equilibrium constants play role in their formation

Water has very low ionization constant so it's possible that other polar solvents with low ionization constants show this behavior
