Study Notes
Writing Acid Names
- Hydro is added to the beginning of the name when the acid is composed of two elements, hydrogen, and a nonmetal.
- **-ic ** is added to the end of the name when the acid is composed of a nonmetal and oxygen and the nonmetal's name ends in -ate
- -ous is added to the end of the name when the acid is composed of a nonmetal and oxygen and name of the nonmetal ends in -ite
- Acetic acid is an exception to the rules and common name.
Naming Acids, Formulae, and Key Examples
- Hydrochloric acid - HCl(aq): Hydro + chlor + ic acid
- Nitric acid - HNO3(aq): Nitr + ic acid
- Phosphoric acid - H3PO4(aq): Phosphor + ic acid
- Hydrosulfuric acid - H2S(aq): Hydro + sulfur + ic acid
- Sulfuric acid - H2SO4(aq): Sulfur + ic acid
- Phosphorous acid - H3PO3(aq): Phosphor + ous acid
- Hydrofluoric acid - HF(aq): Hydro + fluor + ic acid
- Acetic acid - CH3COOH(aq): This is a special case acid where there is a carbon chain.
- Perchloric acid - HClO4(aq): Per + chlor + ic acid
- Iodic acid - HIO3(aq): Iod + ic acid
- Hydrobromic acid - HBr(aq): Hydro + brom + ic acid
- Hypobromous acid - HBrO(aq): Hypo + brom + ous acid
- Sulfurous acid - H2SO3(aq): Sulfur + ous acid
- Chromic acid - H2CrO4(aq): Chrom + ic acid
- Phosphoric acid - H3PO4(aq): Phosphor + ic acid
- Sulfurous acid - H2SO3(aq): Sulfur + ous acid
- Hypochlorous acid - HClO(aq): Hypo + chlor + ous acid
- Hydroiodic acid - HI(aq): Hydro + iod + ic acid
- Chlorous acid - HClO2(aq): Chlor + ous acid
- Nitrous acid - HNO2(aq): Nitr + ous acid
- Nitric acid - HNO3(aq): Nitr + ic acid
- Bromic acid - HBrO3(aq): Brom + ic acid
- Dichromic acid - H2Cr2O7(aq): Di + chrom + ic acid
- Hydrosulfuric acid - H2S(aq): Hydro + sulfur + ic acid
- Hydrobromic acid - HBr(aq): Hydro + brom + ic acid
