What is the chemical equation for the second ionization reaction of phosphoric acid with water?
The second ionization reaction of phosphoric acid (H3PO4) with water is: H2PO4- (aq) + H2O (l) ⇌ H3O+ (aq) + HPO4^2- (aq)
What is the ionization reaction for hydrochloric acid in water?
The ionization reaction for hydrochloric acid in water is: HCl + H2O -> H3O+ + Cl-
What is the ionization energy for phosphorus?
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.
Does phosphorus react with strong acids?
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 is formed from its elements?
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.

What characterizes a strong acid or base?
Complete ionization in water. Very fast reaction with marble chips/powder.
Is phosphorus acid or base?
A phosphorus is a base!
What happens when you mix phosphorus triiodide and water?
When phosphorus triiodide reacts with water, it forms phosphorous acid and hydroiodic acid. This reaction is exothermic and produces a lot of heat. It is also potentially dangerous due to the release of toxic phosphine gas.
Does phosphorous acid come from potash?
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.
What has the highest first ionization energy phosphorous calcium sodium or aluminum?
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.
What is the ionization reaction for hydrobromic acid?
The ionization reaction for hydrobromic acid (HBr) is: HBr (aq) → H+ (aq) + Br- (aq)
Why does phosphorus have a higher ionization energy than sulfur?
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.
