In chemistry, the standard state of a material (pure substance, mixture or solution) is a reference point used to calculate its properties under different conditions. In principle, the choice of standard state is arbitrary, although the International Union of Pure and Applied Chemistry (IUPAC) recommends a conventional set of standard states for general use.[1] IUPAC recommends using a standard pressure po = 1 bar (100 kilopascals). Strictly speaking, temperature is not part of the definition of a standard state. For example, as discussed below the standard state of a gas is conventionally chosen to be unit pressure (usually in bar) ideal gas, regardless of the temperature. However, most tables of thermodynamic quantities are compiled at specific temperatures, most commonly 298.15 K or, somewhat less commonly, 273.15 K. The standard state should not be confused with standard temperature and pressure (STP) for gases,[2] nor with the standard solutions used in analytical chemistry.[3] In the time of their development in the nineteenth century, the superscript plimsoll symbol o was adopted to indicate the non-zero nature of the standard state. The superscript circle º is also commonly used, not least for typographical reasons, and both are equally acceptable.[4] For a given material or substance, the standard state is the reference state for the material's thermodynamic state properties such as enthalpy, entropy, Gibbs free energy, and for many other material standards. The standard enthalpy change of formation for an element in its standard state is zero, and this convention allows a wide range of other thermodynamic quantities to be calculated and tabulated. The standard state of a substance does not have to exist in nature: for example, it is possible to calculate values for steam at 25 °C and 1 bar, even though steam does not exist (as a gas) under these conditions. The advantage of this practice is that tables of thermodynamic properties prepared in this way are self-consistent.

Answer 4

Gaseous, but it dissolves pretty well in water.
