1. Some evidence suggests that phosphorous acid may inhibit proteoid root formation. 2. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds.3. This colourless viscous liquid is the ester of phosphorous acid and phenol. 4. Similarly, phosphorous acid can bond with alcohol molecules to form a phosphite ester. 5. It has Mannich-type reaction of ammonia, formaldehyde, and phosphorous acid . 6. It is usually applied as potassium phosphite, derived from phosphorous acid neutralized with potassium hydroxide. 7. Unlike phosphorous acid , arsenous acid is genuinely tribasic, with the formula As ( OH ) 3. 8. IUPAC recommendations, 2005, are that the latter be called phosphorous acid , whereas the dihydroxy form is called phosphonic acid. 9. It is formally the anhydride of phosphorous acid , H 3 PO 3, but cannot be obtained by the dehydration of the acid. 10. It is a salt of phosphorous acid , HP ( O ) ( OH ) 2 and contains the anion HPO 3 2 ".
