Hope this helps. :)

Phosphorous acid.

Answer 2

Phosphorus acid

Step-by-step explanation:

Hi, as can be seen it's an acid of phosphorus.

Looking the charge of the ion you can determine the valence number of the phosphorus: If there are 3
`O^-2` (equal -6) and the total charge is -3 :

`P - 6 = -3`

`P = -3 + 6= 3`

So it's a phosphorus acid (valence=3) and you can see it's structure in the Figure
