There are two kinds of courts in this country -- state courts and federal courts. Following is a discussion of key differences between the state and federal court systems. State and local courts are established by a state (within states there are also local courts that are established by cities, counties, and other municipalities, which we are including in the general discussion of state courts).
Iron Compounds. A combination of iron and other elements make up important products that are found very useful in a lot of ways. Iron chloride is an important compound that is used in treating sewage systems. It is also used as dye for cloth. It is also used as a coloring agent for paints.
Iron(III) chloride is a yellow solid. It dissolves in water to make a colloid of iron(III) oxide, making the water look muddy. When it is dissolved in an acidic solution, it is bright yellow. When it is very concentrated in a solution, it is dark brown. It is corrosive to skin and metals. It reacts with iron to produce iron(II) chloride. It fumes hydrochloric acid in moist air. It is a weak oxidizing agent. It reacts with copper(I) chloride to make copper(II) chloride. It breaks down when heated to make chlorine and iron(II) chloride. Preparation. It can be made by mixing hydrochloric acid and iron(III) oxide. It can be made by mixing iron and chlorine. It can also be made by reacting iron(II) chloride with chlorine at a low temperature. Uses. It is used in sewage processing. It reacts with slightly basic water to make a floc that can remove things from the water.
