Answer & Explanation:
Hydrochloric acid is formed from the dissolution of hydrogen chloride gas (HCl). The degree of ionizable hydrogen (H⁺) cations of this acid is over 90% and so they are easily ionized.
Hydrochloric acid is highly toxic, with very strong odor, however, its concentration may vary if exposed due to its high volatility (it has a boiling point of -85 ° C) and its ease of absorbing water from the atmosphere (hygroscopy).
Acid exposure can cause skin irritation, respiratory tract irritation if inhaled, blindness if in direct contact with eyes and ingestion may cause corrosion of the mouth and gastrointestinal tract with vomiting, diarrhea and may even cause death.
Also, hydrochloric acid can be found in our stomach during digestive processes. It is also used in dye production, oil extraction and starch and protein hydrolysis by the food industries.
