The H+ ion in water is just a proton and they form clusters. The simplest cluster is H3O+, and is called a hydronium ion. Larger clusters can also occur, like H5O2+ or H9O4+. Water is amphoteric because it can be an acid or a base, Water can be an acid because it donates protons, it can also act as a base because it accepts protons to form hydronium ions. Pure water auto-ionizes by the following equation:
For more help with understanding the auto-ionization of water, I found this website:

Carly, this is the first time seeing your blog for me! I really like this post and it gave me a great understanding of what exactly water is. The picture really enhanced this post as well. I'm a visual person, so I really appreciate seeing what actually happens during this process.
