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

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.
