HCI is acid ? Give scientific reason
Answers
Explanation:
At room temperature, HCl is a colorless, poisonous gas. Dissolve it in water, and, voilà, you have hydrochloric acid. For the record, acids are substances that release hydrogen ions in water. The more hydrogen ions an acid releases in water, the stronger the acid
Hydrochloric Acid. Your stomach makes it naturally to help digest your lunch. It's used industrially to process steel, the material of choice for suspension bridges and cars and trucks. Hydrochloric acid is also used in the production of batteries, photoflash bulbs and fireworks. It's even used to process sugar and make gelatin. Hydrochloric acid, like last month's chlorine compound, sodium chloride, is another "workhorse" chemical because it is incredibly useful in a wide variety of ways.
Unlike sodium chloride, hydrochloric acid is not easy to handle and safety precautions are a MUST! This acid has a sharp, irritating odor and is highly corrosive, meaning, it damages most things it touches. You may be wondering how such a reactive liquid can be stored without ruining its container. Metal containers are out for this acid, but plastic containers, such as those made of PVC (polyvinyl chloride) stand up very well.
This is a photo of the Greer Steel Company steel pickling operation in Dover,
Ohio. In steel-pickling, a hydrochloric acid solution is used to remove rust and
scale to prepare the steel surface for a protective coating. Notice the rusty
appearance of the steel rolls in the foreground and the shiny steel rolls, already
"pickled," on the conveyor belt. About ¼ of the hydrochloric acid produced in the
U.S. is used for pickling steel. (Photo courtesy of Greer Steel Company)
HCl is the compound hydrogen chloride. Each molecule of HCl is composed of a one-to-one ratio of hydrogen and chlorine. (See the diagram at the top left of the page). At room temperature, HCl is a colorless, poisonous gas. Dissolve it in water, and, voilà, you have hydrochloric acid. For the record, acids are substances that release hydrogen ions in water. The more hydrogen ions an acid releases in water, the stronger the acid (see "What is an ion?" below). If you concluded from the above discussion that HCl releases many hydrogen ions in water, you are right!
