Li2so3

Li2SO3 is a chemical compound composed of two lithium (Li) atoms, one sulfur (S) atom, and three oxygen (O) atoms. It is a white or colorless crystalline solid that is sparingly soluble in water.

The molecular formula for Li2SO3 indicates that it contains two lithium ions with a +1 charge each (Li+), one sulfur ion with a +4 charge (S4+), and three oxygen ions with a -2 charge each (O2-). The charges on the ions balance out to form a neutral compound.

The crystal structure of Li2SO3 is monoclinic, with a space group of P21/c. The lattice parameters are a = 5.155 Å, b = 7.025 Å, c = 6.868 Å, and β = 103.52°. The crystallographic axes are defined as follows: a is parallel to the b axis and lies in the plane of the SO3 group; b is perpendicular to the plane of the SO3 group and lies in the direction of the highest symmetry element; c completes the right-handed coordinate system.

Li2SO3 has a molar mass of 109.94 g/mol and a density of 2.22 g/cm3. It decomposes at temperatures above 780°C, forming lithium oxide (Li2O) and sulfur dioxide (SO2).

In terms of its chemical properties, Li2SO3 is a reducing agent and can react with acids to form lithium salts. It is also used in the preparation of other lithium compounds, such as lithium carbonate and lithium hydroxide.
