WebEphedrine Reduction to Methamphetamine with Hypophosphorus Acid and Iodine. By Wizard X. I would recommend a large excess of reducing agent for quick reduction. Charge flask with 100 ml (0.1Lt) of 50% H3PO2 (0.965 mole H3PO2 per 100 ml) fit reflux condenser, add 3x33 grams (99 grams, 0.39 mole) portions of I2 while cooling in ice bath down the ... WebMar 28, 2024 · These reducing agents reduce other molecules. In case of acids if a central atom is present in its maximum oxidation state then it cannot further increase its oxidation state. So, it would not act as a reducing agent. In \[{H_3}P{O_4}\] , phosphorus is present in its maximum oxidation state $( + 5)$. Hence it will not act as a reducing agent.

Good reducing nature of H3PO2 is attributed to the …
WebWith more number of 0 atoms bonded to Z, the compound becomes a stronger acid. The acid strength is also explained by the oxidation number of central atom ( here P ) H3PO2 - +1. H3PO3 - +3. H3PO4 - +5. The acid strength is also explained by counting the number of oxygen atoms bonded to P. hence order of acidity is : H3PO4 > H3PO3 >H3PO2. WebH 3P O2. Solution: Acids which contain P—H bonds have strong reducing properties. Hypophosphorus acid (H 3 PO 2) is a good reducing agent as it contains two P—H bonds. It has one P—OH bond, so it is monobasic. WebOct 16, 2024 · H 3 PO 3 contains one P – H bond and hence acts as a reducing agent but H 3 PO 4 does not contain a P–H bond. ... 1 mol each of H3PO2, H3PO3 and H3PO4 will neutralise x mole of NaOH, y mol of Ca(OH)2 and z mol of Al(OH)3. asked Oct 15, 2024 in P - block elements by KumarManish (57.9k points) fee tes creations
