EnglishEdit

EtymologyEdit

From Latin bis (twice).

PrefixEdit

Latin number prefix
Previous: uni-
Next: tri-

bi-

  1. two
  2. (chemistry, proscribed) half

Usage notesEdit

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.
