Standard States

Postby Annalyn Diaz 1J » Fri Jan 25, 2019 11:44 am

I know that the standard state for a gas is 1atm. How do you determine standard states of something other than a gas, such as a liquid or solid, or an element?

Pure liquid and solid are naturally considered as in their standard state. The standard state for a solution is defined as 1 M. The standard state for an element is its most stable phase at 1 atm.
