Phosphorus(III) oxide. magnesium oxide - This is a basic oxide. Some metal oxides react with water to form alkaline solutions. Some non-metal oxides, such as nitrous oxide (N 2 O) and carbon monoxide (CO), do not display any acid/base characteristics. What are the disadvantages of primary group? and the acidic nature of an oxide of phosphorus? silicon oxide - This does not exist. Due to high electronegativity, oxygen can react with almost all the elements except noble gases. Where did Beulah and Bertie live in the story backfire by shirly tapping? Give a reason for your answer..... [1] (d) Phosphorus(V) oxide is a solid. Quartz has many different structures - see the link below. In phosphorous acid, the two hydrogen atoms in the -OH groups are acidic, but the third hydrogen atom is … Acidic oxides can also react with basic oxides to produce salts of oxoanions : 2 MgO + SiO 2 → Mg 2 SiO 4 Neutral Oxide is one which neither has an acidic characteristic or a basic one. White phosphorus can combine with excess oxygen to form a phosphorus oxide (product X). P2O5 + 3H2O = Subtract from it the three molecules of water and work P2O5 – phosphorus oxide (V). It reacts with moisture to form metaphosphoric acid. 1.
