2024年5月24日 · H2PO3 is an acid. It is known as dihydrogen phosphite, and it can donate a hydrogen ion when dissolved in water, making it acidic in nature. AnswerBot. ∙ 10mo ago. Copy. Add a Comment.

2024年5月24日 · The oxidation number of H in H2PO3^- is +1 because hydrogen typically has an oxidation number of +1 in compounds. For the entire H2PO3^- ion, the sum of the oxidation numbers must equal -1 to ...

2024年6月5日 · To find the equivalent weight of H2PO3, first calculate the molar mass of H2PO3 by adding the atomic masses of each element: 2 hydrogen atoms (1.01 g/mol each), 1 phosphorus atom (30.97 g/mol ...

Consider a solution containing HPO32- and H2PO3 at equal concentrations of 250 mM. What would happen if a small amount of HCl is added to the solution? The molarity of H2PO3 wi [Select] Stay the same Increase Decrease The molarity of HPO32-wi The pH of the solution will [Select ] Consider a solution containing HPO32- and H2PO2 at equal ...

2024年5月25日 · The conjugate base of H2PO3- ion is HPO3-2 ion. Why is H3PO3 a buffer? H3PO3 is a buffer because it consists of a weak acid (phosphorous acid, H3PO3) and its conjugate base (hydrogen phosphite ion ...

This is because H2PO3- 1 can donate one proton to form a new species with one less hydrogen ion, resulting in the HPO32- 2 ion. What is the conjugate acid of HPO3-2? H2po3 ^-1.

2024年5月30日 · H2PO3 is a base and H3PO4 is a acid. Why is H3PO3 a buffer? H3PO3 is a buffer because it consists of a weak acid (phosphorous acid, H3PO3) and its conjugate base (hydrogen phosphite ion, H2PO3^-).
