Jod-pentoksidjeoksid joda hemijske formuleI₂O₅,gde jeoksidacioni brojjoda +5.

Dobijanje

Može se dobiti zagrevanjem jodne kiseline natemperaturiod oko 170 °C, jer se ona tada raspada uz gubitakvode^[5]:

\mathrm {2HIO_{3}\longrightarrow \;H_{2}O+I_{2}O_{5}}

Svojstva

Jod-pentoksid je belakristalna supstanca,za koju važi da je postojanija nego bilo koji drugioksid hlorailibroma.Ipak, iznad 200 °C se raspada na jod ikiseonik.Sa vodom gradi jodnu kiselinu, te se smatra njenim anhidridom.^[5]

Particioni koeficijent^[6](ALogP)	1,3
Rastvorljivost^[7](logS,log(mol/L))	4,1
Polarna površina^[8](PSA,Å²)	77,5

Primena

Ovaj oksid je jakooksidacionosredstvo, pa može da oksidujeugljen-monoksid,što je važno u otkrivanju ovoggasausmeši,čak i u malimkoličinama:

\mathrm {I_{2}O_{5}+5CO\longrightarrow \;I_{2}+5CO_{2}}

Reagenskoji se koristi u ovu svrhu i koji sadrži jod-pentoksid se nazivahulmanit.^[5]
