• Liquid at room temperature •Gas at room temperature • Argon has approximately the same solubility in water as oxygen and is 2.5 times more soluble in water than nitrogen. Argon is colorless, odorless, nonflammable and nontoxic as a solid, liquid or gas. Argon is chemically inert under most conditions and forms no confirmed stable compounds at room temperature.
When H2O acts as a base, it gains one H, which forms its conjugate acid, H30. ... Conjugate acid-base pairs: H2SO4/HSO4 andH3O+/H2O ... CO32-(aq) + H2O(1) 2 HCO3 (aq) + OH(aq).
