Hydrochloric acid (HCl) is a common acid used in the laboratory to make acidic solutions. Aqueous HCl solutions show low pH values because HCl is a strong acidic compound. You can easily check this by using a pH meter. In theoretically, pH value can be found by substituting concentration ...
What determines if an acid is weak or strong depends on how it dissociates or breaks apart in water. Weak acids partially dissociate while strong acids completely dissociate. Hydrochloric acid (HCl) is a very strong acid that completely breaks down in water. Hydrochloric acid, also known as ...
