(I) After A Chemical Compound

  1. Mar 28, 2010 #1
    I was wondering what (I) means when it is written after a chemical compound, for example, H2SO4 (I). Thanks!

    It's not an I, it's an L, and indicates that the Hydrogen Sulfate is in a pure liquid state.

    It couldn't be an I, as the four states are (g), (l), (s), and (aq).

    Now, there is a case where (I) is used in a compound, such as Copper(I) Iodide, and that indicates the charge of the copper atom.
