Write the names that correspond to the formulas HIO3,
HIO, and HC2H3O2.
The first step in writing a name from a
chemical formula is to decide which type of compound the formula
represents. All three of these formulas represent oxyacids.
The name for IO3- is iodate, so HIO3
is iodic acid.
HIO has two fewer oxygen atoms than iodic acid, so it is hypoiodous acid.
The name of the oxyanion C2H3O2-
is acetate, so HC2H3O2 is acetic acid. CH3CO2H and CH3COOH
are also commonly used as formulas for acetic acid.
