Acids are used as catalysts in industrial and organic chemistry; for example, sulfuric acid is used in very large quantities in the alkylation process to produce gasoline. Strong acids, such as sulfuric, phosphoric and hydrochloric acids also effect dehydration and condensation reactions.he Arrhenius definition defines acids as substances which increase the concentration of hydrogen ions (H +), or more accurately, hydronium ions (H 3 O +), when dissolved in water. The Broensted-BrÃ¸nsted lowry definition is an: expansion an acid is a substance which can act as a proton. donor
1 Acid is sour to the taste and corrosive in nature. 2  The pH value for acids is less than 7. 3  Generally, all acids readily react with metal to release hydrogen gas. 4  For example, metal zinc reacts with hydrochloric acid to form zinc chloride and hydrogen gas. The acids we use in the laboratory are very strong acids like hydrochloric acid and sulfuric acid. 2  Strong acids are corrosive and can burn your skin. 3  Bases, on the other hand, are the chemical opposite of acids. 4  They are bitter in taste and soapy to touch.
