Study Notes
Oxyacids and Their Nomenclature
- Carbonous acid (H2CO2) is derived from the carbonite ion (CO22-).
- Oxyacids are named based on the oxyanion they originate from; ions ending in -ite have one less oxygen than those ending in -ate.
- Nitrous acid (HNO2) comes from the nitrite ion (NO2-).
Specific Acid Formulas and Names
- Hypophosphorous acid (H3PO2) originates from the hypophosphite ion (PO23-), having two fewer oxygens than the phosphate ion (PO43-).
- Chlorous acid (HClO2) is derived from the chlorite ion.
Acid-Formula Pairing
- Correct acid and formula pairing includes hyposulfurous acid, which is represented as H2SO2.
- Other pairs of acids and their formulas may not be accurately matched and should be verified.
Common Acids and Their Properties
- Aqueous hydrogen chloride (HCl) is a prominent binary acid.
- Chromous acid is represented by the formula H2CrO3, formed from the chromite ion (CrO32-).
- The hypochlorous anion (ClO¯) forms hypochlorous acid (HClO).
Additional Acid Information
- The formula for acetic acid is CH3COOH, a well-known organic compound.
- Hydrochloric acid is named by the pattern "hydro + root + ic acid" used for binary acids.
- Chromic acid has the formula H2CrO4, while permanganic acid is represented as HMnO4.
- Sulfuric acid has the formula H2SO4, a widely used industrial acid.
- Hydrosulfuric acid is represented by H2S, commonly known as hydrogen sulfide.
- Hyposulfurous acid's formula is H2SO2, and dichromic acid corresponds to H2Cr2O7, derived from the dichromate ion (Cr2O72-).
