Portage Learning Chem 210 - Module 2 Problem Set What is the shape of water? Bent. The bond angle is 104.5 degrees. What is autoionization, and how is it important for water? Autoionization is the ability of a compound to react with itself to form ions. One water molecule reacts with a second molecule to form two ions: H3O+ and OH-. These ions exist in small amounts in pure water and influence the chemistry of water. Name the three non-covalent forces ...
