Question

Show two steps how H3PO3 ionise.​

Answer 1

Explanation:

Phosphorous acid is the compound described by the formula H3PO3. This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds. Organic derivatives of phosphorous acid, compounds with the formula RPO3H2, are called phosphonic acids.

Answer 2

dear mate, here's your answer :-

Other names

Dihydroxyphosphine oxide

Dihydroxy(oxo)-λ5-phosphane

Dihydroxy-λ5-phosphanone

Orthophosphorous acid

Oxo-λ5-phosphanediol

Oxo-λ5-phosphonous acidPhosphorous acid is the compound described by the formula H3PO3. This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula.
