HYPOPHOSPHITE在英语中的意思是什么？

次磷酸钠

Hypophosphite

次磷酸根离子是H2PO2-，次磷酸减去一个氢离子。 次磷酸盐是含有这种离子的化合物，磷的氧化态为+1，或类似的共价。 两个氢原子直接连接在磷原子上。 相同离子的IUPAC名称是次膦酸盐。 这实际上不用于次磷酸根离子本身，其中两个氢都保留，但是用于取代的离子。 例如，“二甲基亚膦酸根”离子为2PO2-。 次磷酸盐可以通过在温碱水中加热白磷来制备：P4 + 3 OH- + 3 H2O→3 H2PO2- + PH3次磷酸盐是还原剂：H2PO2- + 3OH-→HPO32- + 2H2O + 2e-次磷酸盐用于无电解 镍镀层作为还原剂，从Ni盐沉积例如Ni金属。 次磷酸盐离子在热力学上不稳定，加热至磷化氢气体和磷酸盐时不成比例：2 H 2 PO 2→→PH 3 + HPO 42 -...

The hypophosphite ion is H2PO2−, hypophosphorous acid minus one hydrogen ion. Hypophosphites are the compounds containing this ion, with phosphorus in oxidation state +1, or similar covalent ones. Two hydrogens are attached directly to the phosphorus atom. The IUPAC name for the same ion is phosphinate. This is virtually not used for hypophosphite ion itself, with both hydrogens remaining, but for substituted ions. For example, "dimethylphosphinate" ion would be 2PO2−. Hypophosphites can be made by heating white phosphorus in warm aqueous alkali: P4 + 3 OH− + 3 H2O → 3 H2PO2− + PH3 Hypophosphites are reducing agents: H2PO2− +3OH− → HPO32− + 2H2O + 2e- Hypophosphites are used in electroless nickel plating as the reducing agent to deposit for example Ni metal from Ni salts. The hypophosphite ion is thermodynamically unstable, and disproportionates on heating to phosphine gas and phosphate salts: 2 H2PO2− → PH3 + HPO42−...
