App Description
Are you struggling to remember the different polyatomic ions in your chemistry class? There are so many unique ions that it becomes extremely difficult to remember their charges, names, and other aspects.
This is a new chemical discovery-Ions, the app. With 38 different polyatomic ions, it will become quite simple for you to learn and remember the "single units" of acid and base chemistry.
Ions has the best interface of any polyatomic ion app on the app store. Formulas are written in super/subscript to eliminate confusion and they also offer large, bold font for your viewing pleasure.
This app offers quizzes and a fantastic new flash cards tool to help you study and remember the ions in a fast and simple way. You can also create a group of your FAVORITE flash cards!
