'''Fosforsyrlighet''', summaformel H<sub>3</sub>PO<sub>3</sub>, är en [[syra]] som bland annat innehåller [[fosfor]].<br />
<br />
Salter av fosforsyrlighet kallas [[fosfonit]]er.<br />
<br />
==Tautomerer==<br />
Fosforsyrlighet existerar i två [[tautomer]]a former. I vattenlösning utgör formen P(OH)<sub>3</sub>, där alla [[väte]]atomer är bundna till syre endast en mindre del, medan huvuddelen föreligger i formen HP(O)(OH)<sub>2</sub>, där en väteatom är bunden direkt till fosofor. Denna tautomer kallas också för '''fosfonsyra'''. Denna beteckning används särskilt som utgångspunkt för substiuterade [[organisk kemi|organiska föreningar]], såsom metylfosfonsyra, CH<sub>3</sub>P(O)(OH)<sub>2</sub>.<br />
<br />
==Fosforsyra och fosforsyrlighet==<br />
Skillnaden mellan fosforsyrlighet och [[fosforsyra]], H<sub>3</sub>PO<sub>4</sub>, är att fosforatomen har ett lägre [[oxidationstal]] (+3) i fosforsyrlighet än i fosforsyra (+5). Fosforsyrlighet är en svagare syra än fosforsyra. <br />
