Is an electrolyte a compound of ions?

A compound that can conduct electricity in aqueous solution or molten state is called an electrolyte.
Ionic compounds can conduct electricity in aqueous solutions or in molten state; covalent compounds: some can also conduct electricity in aqueous solutions
The properties of conductivity have nothing to do with solubility. Strong electrolytes generally include strong acids, strong bases, and most salts. Weak electrolytes generally include weak acids (partially ionized compounds in water). In addition, water is a very weak electrolyte.
Note: It is not necessarily the electrolyte that can conduct electricity to judge whether a certain compound is an electrolyte. It can not only conduct electricity in the aqueous solution, but also further investigate the crystal structure and chemical bond properties of the compound. For example, it is necessary to judge whether barium sulfate, calcium carbonate and iron hydroxide are electrolytes. Barium sulfate is insoluble in water, the ion concentration in the solution is very small, and the aqueous solution is non-conductive and seems to be non-electrolyte. However, the small part of barium sulfate that is soluble in water is almost completely ionized. Therefore, barium sulfate is an electrolyte. Calcium carbonate and barium sulfate have similar are also electrolytes. From the structural point of view, barium sulfate is hardly soluble in other salts. Any ionic or strongly polar covalent compound, though insoluble, is an electrolyte.
The chemical bond between Fe3+ and OH- is covalent, and its solubility is smaller than that of barium sulfate.
It is also necessary to make specific analysis to determine whether the oxide is an electrolyte. Non-metallic oxides, such as SO2, SO3, P2O5, CO2, etc., are covalent compounds, which are not conductive in liquid state, so they are not electrolytes. Some oxides are not electrolytes even though they are conductive in aqueous solution. Because these oxides react with water to generate new conductive substances, the conductive ones in the solution are not original oxides, for example, SO2 itself can not be ionized, but they react with water to generate sulfuric acid, which is electrolyte. Metal oxides, such as Na2O,MgO,CaO,Al2O3, are ionic compounds. They conduct electricity in a molten state and are therefore electrolytes.
It can be seen that electrolytes include ionic or strong-polar covalent compounds; non-electrolytes include weak-polar or non-polar covalent compounds. Electrolyte aqueous solutions can conduct electricity because electrolytes can dissociate into ions. Whether a substance can ionize in water is determined by its structure. Therefore, recognizing electrolytes and non-electrolytes by their structure is the essence of the problem.
Besides, some conductive substances, such as copper and aluminum, are not electrolytes, because they are not conductive compounds, but simple substances, which do not meet the definition of electrolyte.
Electrolytes are those compounds that are electrically conductive in aqueous solution or molten state, such as acids, bases, and salts.
The process by which electrolytic electric energy is converted into chemical energy. Even if direct current flows through an electrolytic cell, the electrochemical reaction is carried out on the electrode-solution interface. For example, for the electrolysis of water, the cathode of the electrolytic cell is an iron plate, the anode is a nickel plate, and the electrolyte is a sodium hydroxide solution. When energized, under the action of an external electric field, the positive and negative ions in the electrolyte migrate to the cathode and anode respectively, and the ion carries out electrochemical reaction on the electrode-solution interface. The reduction reaction is carried out on the cathode.
Water electrolysis is to decompose water into H2(g) and O2(g) under the action of external electric field. Electrolysis is a very powerful means to promote redox reaction. Many difficult redox reactions can be realized by electrolysis. For example, molten fluoride can be oxidized to elemental fluorine on the anode, and molten lithium salt can be reduced to metal lithium on the cathode. Electrolysis industry plays an important role in national economy. Many non-ferrous metals and rare metals are smelted and refined, and the preparation of basic chemical products, as well as electroplating, electropolishing and anodizing are realized by electrolysis.

Is calcium hydroxide written as a chemical formula or ion symbol in the ion equation?

I'll tell you this, in the chemistry of the first high, the calcium hydroxide, and on the left, as long as the solution is absolutely removed, because the calcium hydroxide is slightly soluble, and the calcium salt, can be completely ionized. On the right, it depends on the concentration, the concentration is the precipitation, the concentration is the solution
