Question #00a96

Answer 1

Ther is no net macroscopic chemical change.

Explanation:

The salt and the acid simply speciate in aqueous solution, i.e.

`NaNO_3(aq) + HCl(aq) stackrel(H_2O)rarr Na^+ + NO_3^(-) +H^+ + Cl^-`

You can write the metathesis reactions if you like but there is neither a precipitate nor neutralization. We represent the `"protium ion"` as `H^+`, and we could equally represent it as the `"hydronium ion"`, `H_3O^+`. We use these as shorthands to represent the acidium species in solution, which is probably a cluster of 3-4 water molecules, WITH AN EXTRA `H^+` ion, i.e. `H_7O_3^+` or `H_9O_4^+`....The extra protons exchanges rapidly, tunnels if you like, between different water clusters.
