Oxoacids can be formed that involve several central atoms of the same chemical element. An example is H;P3O9, which can be written P;O6(OH)3. (Sodium salts of these polyphosphoric acids are used as “builders" in detergents to improve their cleaning power.) In such a case, we would expect acid strength to correlate approximately with the ratio of the number of lone oxygen atoms to the number of central atoms (this ratio is 6:3 for H;P3O9, for exam- ple). Rank the following in order of increasing acid strength: H,PO, H,P,О9, Н,Р,06, H.P,0-, H;Р,О 10- Assume that no hydrogen atoms are directly bonded to phosphorus in these compounds.

Question
Transcribed Image Text:Oxoacids can be formed that involve several central atoms
of the same chemical element. An example is H;P3O9,
which can be written P;O6(OH)3. (Sodium salts of these
polyphosphoric acids are used as “builders" in detergents
to improve their cleaning power.) In such a case, we would
expect acid strength to correlate approximately with the
ratio of the number of lone oxygen atoms to the number
of central atoms (this ratio is 6:3 for H;P3O9, for exam-
ple). Rank the following in order of increasing acid
strength: H,PO, H,P,О9, Н,Р,06, H.P,0-, H;Р,О 10-
Assume that no hydrogen atoms are directly bonded to
phosphorus in these compounds.
