### H30+ and H+

For the Ka formula, why is H30+ and H+ the same thing?

H3O+ and H+ are similar in that they define whether something is an acid. Although H3O+ is not technically a proton like H+ is, it can be thought of as a proton bound to a water molecule.

Also you can see it as H3O+ and H+(aq) which are equivalent because H3O+ is just H2O + H+

### Re: H30+ and H+

When HCl is deprotonated, we often write it as H+ and Cl- for simplicity. However, H+ does not exist in form of a single proton, it will bind with water and form H3O*. So it is a actually transfer of proton.

H+ does not usually exist as a single proton and binds with water.
