Have you ever reviewed a quiz or test covering the subject of naming and writing inorganic chemical formulas that contained disappointing results? Instead of the name iron(II) nitrate for Fe(NO₃)₂, the quiz had iron nitrogen oxide II. Or the formula of for sodium sulfate, Na₂SO₄, was written as Na₄SO.  These error types can be significantly reduced by employing our Chemical Formula App to minimize the opportunities to make such errors. The skill of writing and naming formulas is a corner stone in the process of learning chemistry. Very little real progress can be made without this skill. All of chemistry depends on the ability to process formulas.

Our app can be used by a single student or groups of two or three students. Multiple opportunities and immediate feedback set the stage for success.   App operation is intuitive leaving the user to focus entirely on learning chemistry.
