Standard State

Postby Kyra LeRoy 1E » Sat Jan 20, 2018 3:58 pm

How do we know if a substance is in its standard state? I know its the most stable form, but is there a way to tell if it is in that form? Or do we just have to memorize the standard states for common substances?

Thanks!

I was also wondering about this. In class, I believe that Dr. Lavelle told us that the most common ones were C(s),N2(g),O2(g),F2(g),Cl2(g),Br2(l),and I2(s). Are these the only ones we would encounter in tests? If not, how do we determine whether it is in standard state or not?

I am pretty sure that you have to memorize them. For example the noble gases are gas in standard state with the exception of Br2 (liquid) and Iodine (solid). If it was an element we don't usually talk about, I think they would give us on the test
