Standard States

[Rebecca Doan 2L]

How do you know an element's standard state? are you just supposed to memorize them or...?

[Chris Pleman 3E]

I believe we should be told on the test, but beyond that, a table of standard enthalpy of formation would have a zero next to a compound in its standard state.

It might be helpful to memorize the standard states for the more common elements. Gas is the standard state for fluorine, chlorine, hydrogen, nitrogen, oxygen, the halogens, and the noble gases. Mercury and bromine are liquid at standard state the rest are solids. However, there will probably be an indication of whether something is in its standard state within the question.

It may be helpful just to remember the two that are liquids (mercury and bromine) and that the noble gases plus F, N, O, and Cl are gases and the rest are solids.

In lecture it was also mentioned that carbon's standard state is graphite.
