The ionization reaction for phosphorous acid (H3PO3) is: H3PO3 -> H+ + H2PO3-
The second ionization reaction of phosphoric acid (H3PO4) with water is: H2PO4- (aq) + H2O (l) ⇌ H3O+ (aq) + HPO4^2- (aq)

The first ionization energy for phosphorus is 10.49 eV, which is the energy required to remove one electron from a phosphorus atom in its neutral gaseous state.
Phosphorus does react with strong acids, such as hydrochloric acid or sulfuric acid, to form phosphoric acid. The reaction can produce heat and may release toxic phosphine gas. It is important to handle phosphorus with care when reacting with strong acids.
Phosphorus acid triiodide (HI₃PO₃) is formed by reacting phosphorus trichloride (PCl₃) with potassium iodide (KI) in the presence of water. This reaction results in the substitution of chlorine atoms in phosphorus trichloride with iodine atoms from potassium iodide, leading to the formation of phosphorus acid triiodide.

Complete ionization in water. Very fast reaction with marble chips/powder.
A phosphorus is a base!
No, phosphorous acid does not come from potash. Potash refers to compounds containing potassium, while phosphorous acid is derived from phosphorus. Phosphorous acid is typically produced by the reaction of white phosphorus with a strong base.
Phosphorus triiodide reacts violently with water, so the reaction is exothermic. If a large amount of phosphorus triiodide is mixed, an explosion will most likely occur. If it is a small amount, then it will be similar to the reaction of potassium with water.
Phosphorus has the highest first ionization energy among phosphorus, calcium, sodium, and aluminum. This is because phosphorus has a higher effective nuclear charge compared to the other elements, making it more difficult to remove an electron from its outer shell.
HCl (aq) + H2O (L) ---------> H3O+ (aq) + Cl- (aq)
Phosphorus has a higher ionization energy than sulfur because phosphorus has a smaller atomic radius and greater nuclear charge compared to sulfur. This means that the electrons in phosphorus are held more tightly by the nucleus, requiring more energy to remove an electron. Additionally, the electron configuration of phosphorus leads to greater electron repulsion, further increasing its ionization energy.
