Question

Are protons donors? Do they increase the concentration of `H^+`(aq) in solution?

Answer 1

Acids are formally `"proton donors"`.

Explanation:

And thus in water, the action of a hydrogen halide, the typical acid, may be defined as:

`HX+H_2O rightleftharpoons H_3O^(+) + X^-`

The equilibrium might lie to the right or to the left, but it does operate, and we conceive that `H_3O^+`, the characteristic cation, is the `"acidium species"` in water. Most of the time, we are concerned with water solvent. It is not the only solvent available.
