Definition and Usage:
Hydrochloric acid is a chemical compound consisting of hydrogen and chlorine elements, commonly known as hydrochloric acid. It is gaseous under normal pressure and at room temperature. Today, it is used in all areas from the iron and steel sector to the PVC sector, organic material production and the food sector. In addition to these conveniences, hydrochloric acid actually has a toxic content. It causes damage to many surfaces, including the human body. When working with this acid, great care should be taken and the necessary precautions should be taken. It has both a toxic and irritating effect. It causes burns on the skin and irritation in the respiratory system. In order to obtain hydrochloric acid, hydrogen gas must first be obtained. Hydrogen chloride normally boils at 110 degrees and melts at -27 to 32 degrees.
Hydrochloric acid is a compound consisting of one chlorine atom and one hydrogen atom, shown with the formula HCI. This compound dissolves at a high rate of approximately 450 liters in one liter of water at room temperature. Like other acids, it gives a color called acid color. It has a high effect on bases such as ammonia and sodium carbonate. If hydrochloric acid is dropped into water, it gives H+ ion. It releases hydrogen when it affects metals such as iron, zinc, aluminum, magnesium. Although it reacts with oxygen in the air together with copper, hydrogen is not released here. Hydrochloric acid also has a rust-removing effect. When carbonates react with this compound, carbon dioxide is released. When it interacts with organic compounds, chlorinated products can be obtained.
