Chemistry Quiz: Acids Overview

Study Notes

Strong and Weak Acids

Hydrochloric acid (HCl) is a strong acid commonly found in stomach fluids.
Hydrobromic acid (HBr) is also a strong acid, often used in organic synthesis.
Hydroiodic acid (HI) is a powerful acid used in iodination reactions.

Sulfur and Nitrogen Compounds

Hydrosulfuric acid (H₂S) is a weak acid known for its distinct rotten egg smell.
Nitric acid (HNO₃) is a strong acid used in fertilizers and explosives.
Nitrous acid (HNO₂) is a weak acid formed in aqueous solutions of nitrogen oxides.

Phosphoric Acids

Sulfuric acid (H₂SO₄) is a strong acid crucial in manufacturing and car batteries.
Sulfurous acid (H₂SO₃) is a weak acid produced when sulfur dioxide dissolves in water.
Phosphoric acid (H₃PO₄) is a versatile acid used in food flavoring and fertilizers.
Phosphorous acid (H₃PO₃) serves as both an acid and a phosphonate in industrial applications.

Hydrocyanic and Acetic Acids

Hydrocyanic acid (HCN) is a highly toxic compound used in various chemical processes.
Acetic acid (CH₃COOH or HC₂H₃O₂) is an important organic compound used in vinegar and as a chemical reagent.

Carbonic and Hypochlorous Acids

Carbonic acid (H₂CO₃) is formed when carbon dioxide dissolves in water, plays a role in carbonation of beverages.
Hypochlorous acid (HClO or HOCl) is a weak acid with disinfectant properties, often used in water treatment.

Chlorine Compounds

Chlorous acid (HClO₂) is a weak acid used in bleaching and disinfection processes.
Chloric acid (HClO₃) is a strong oxidizing agent with uses in explosives.
Perchloric acid (HClO₄) is a strong acid and a powerful oxidizer, important in rocket fuel.

Bromine and Iodine Acids

Hypobromous acid (HBrO) is a weak acid used in water purification.
Bromous (HBrO₂), bromic (HBrO₃), and perbromic acids (HBrO₄) are characterized by their increasing oxidation states of bromine.

Iodine Compounds

Hypoiodous acid (HIO or HOI) is a weak acid with potential use as an antiseptic.
Iodous acid (HIO₂) and iodic acid (HIO₃) are related compounds with different iodine oxidation states.
Periodic acid (HIO₄) is used in organic synthesis and as a reagent.

Fluorine and Boron Acids

Hypofluorous acid (HFO or HOF) is a weak acid related to fluorine chemistry.
Boric acid (H₃BO₃) acts as a weak acid and is used in antiseptics and insecticides.

Special Organic Acids

Cyanic acid (HOCN) is produced during the hydrolysis of cyanates.
Thiosulfuric acid (H₂S₂O₃) is a weak acid involved in various chemical reactions.
Oxalic acid (H₂C₂O₄) is a naturally occurring acid found in many plants, used as a cleaning agent and in the textile industry.
