What is a standard state of a substance?

1.	What is a standard state of a substance?
Answer» The standard state of a substance is that state in which the substance has unit activity or concentration at 25 °C. i.e., For solution having concentration 1 molar, gas at 1 atm, pure liquids or solids are said to be in their standard states.
