Question

Assuming the compound is dissolved in water, what is the formula for phosphorous acid? H3P H3PO4 HP H3PO3

Answer 1

H3PO4

Step-by-step explanation:

Answer 2

Answer: The chemical formula for phosphorous acid is
`H_3PO_3`

Step-by-step explanation:

An acid is defined as the substance which releases hydrogen ions on dissolving in water.

Phosphorous acid is an acid which is formed by the combination of hydrogen ions
`(H^+)` and phosphite ion having formula
`PO_3^(3-)`

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

Hence, the chemical formula for phosphorous acid is
`H_3PO_3`
