Usage notes
[edit]In an old, common method used to indicate the presence of an acidic hydrogen, sodium hydrogen sulfate is called "sodium bisulfate" and sodium hydrogen carbonate is called "sodium bicarbonate". This method is not recommended by IUPAC and does not denote a “doubling up” of a specific group, which is reserved for the Greek prefix di-, as in carbon dioxide (“CO2”).
The prefix bi in the older system comes from the observation that there is two times as much carbonate (CO3) in sodium bicarbonate (NaHCO3) and other bicarbonates as in sodium carbonate (Na2CO3) and other carbonates.
As a prefix for periods, bi- is ambiguously used to mean either “once every two periods” or “twice every period”; this is particularly acute for biweekly, bimonthly, and biannual. To avoid ambiguity, semi- or twice can be used to unambiguously mean “every half period” (thus twice every period) or “twice every period”, but there is no general way to refer unambiguously to “once every two periods”. In some cases a separate word is unambiguous, as in fortnightly (“every two weeks”), or biennial (“every two years”), but there is no word that unambiguously refers to “every two months”. Due to the ambiguity, some prefer to use explicit phrases, like “every two months” or “twice a month”.

The pronunciation /bi-/ (instead of expected /bə-/) is probably due to the influence of the preposition by.
