Mention the oxyacids of phosphorus and the oxidation states of phosphorus in them. 

Oxoacids of Phosphorus

The oxidation state of phosphorus vary from

Phosphorus has the oxidation state of +3 in

Phosphorus has

Atomicity of phosphorus is

Phosphorus pentoxide is :

What is the basicity of phosphorus acid ?

White phosphorus has.

The oxyacid of phosphorous in which phosphorus has lowest oxidation state is.

Phosphorus forms a number of oxoacids which differ in their structures and oxidation state of phosphorus. All the acids contain phosphorus atom//atoms linked tetrahedrally to four other atoms or groups. Each of them has at least one P=O or P rarr O unit and one P-OH unit. The OH group is ionisable but H atom linked directly to P is non-ionisabl. Structures of all the acids are considered to be derived either from phosphorus acid or phosphoric acid. Which one has + 3 oxidation state ?
