Hydrogen Chloride is an important chapter in ICSE Class 10 Chemistry. This will help you to get better marks in ICSE Class 10В Board Exams ICSE Class 10 Chemistry Important Questions Hydrogen Chloride This will help you to understand the pattern of questions in ICSEВ Class 10В ChemistryВ and prepare accordingly. You should always go through questions that have come in previous years. Nitric and sulfuric acids are other examples of strong acids.Students of ICSE Class 10 should refer to Hydrogen ChlorideВ ICSE Class 10 Chemistry QuestionsВ below which have come in past board exams. Because all the hydrogen atoms in hydrogen chloride are converted into hydrogen ions, hydrochloric acid is called a strong acid. These are positively charged atoms of hydrogen that are very reactive and are responsible for all acids behaving in much the same way. Like most acids, hydrogen chloride forms hydrogen ions in water. These are all examples of basic compounds, which neutralize hydrochloric acid, and form metal chlorides. Both moist hydrogen chloride and hydrochloric acid also react with many compounds including metal oxides, hydroxides, and carbonates. For example, zinc metal dissolves in hydrochloric acid to form hydrogen gas and zinc chloride. Metal chlorides are formed when a metal displaces the hydrogen from the hydrogen chloride. When hydrochloric acid reacts with metals, hydrogen gas and compounds known as metal chlorides are usually generated. Consequently, dry hydrogen chloride gas can be stored in metal containers, whereas solutions of highly corrosive hydrochloric acid must be handled in acid-proof materials such as ceramics or glass. While dry hydrogen chloride gas is fairly unreactive, moist hydrogen chloride gas (and hydrochloric acid solutions) react with many metals. Chemists always wear protective rubber gloves and safety glasses when using either hydrogen chloride or hydrochloric acid, and generally work in a well ventilated area to reduce exposure to fumes. Concentrated hydrochloric acid solutions cause burns and inflammation of the skin. Exposure to hydrogen chloride vapor can damage the nasal passages and produce coughing, pneumonia, headaches and rapid throbbing of the heart, and death can occur from exposure to levels in air greater than about 0.2%. Both substances strongly irritate the eyes and are highly toxic if inhaled or ingested. Both hydrogen chloride and hydrochloric acid are corrosive, and so must be treated with great care. Hydrochloric acid is a colorless, fuming liquid having an irritating odor. The gas condenses to a liquid at -121вЏ (-85вЊ) and freezes into a solid at -173.2вЏ (-114вЊ). Hydrogen chloride is a colorless, nonflammable gas with an acrid odor. When smaller amounts of hydrogen chloride are dissolved in water, the solution is known as dilute hydrochloric acid. Commercial hydrochloric acid usually contains 28-35% hydrogen chloride by weight, and is generally referred to as concentrated hydrochloric acid. The resulting solution is known as hydrochloric acid and this also is generally given the chemical formula HCl. Hydrogen chloride is very soluble in water, the latter dissolving hundreds of times its own volume of hydrogen chloride gas. A much more convenient way to use hydrogen chloride is by dissolving it in water to form a solution. Consequently it is generally stored under pressure in metal containers. At room temperature (about 77вЏ ) and at a pressure of one atmosphere, hydrogen chloride exists as a gas. This means that a molecule of hydrogen chloride contains one atom of hydrogen and one atom of chlorine. Hydrogen chloride is represented by the chemical formula HCl.
