It is important to remember that the trend only applies for oxides in their highest oxidation states. Since the difference in electronegativity between these elements is low, the bonds that are formed between them are covalent. (b) When metals combine with oxygen, they form basic oxides. Compound oxides are metallic oxides that behave as if they are made up of two oxides, one that has a lower oxidation and one with a higher oxidation of the same metal, e.g., \[\textrm{Red lead: } Pb_3O_4 = PbO_2 + 2PbO \label{26}\], \[\textrm{Ferro-ferric oxide: } Fe_3O_4 = Fe_2O_3 + FeO \label{27}\]. Metallic oxides are basic in nature because they react with dilute acids to form salt and water. Silicon, phosphorus, sulphur, and chlorine oxides are acidic. Many metals and non-metals react with oxygen in the air when they are heated to produce metal oxides and non-metal oxides. Basic oxides are the oxides of metals. For example: Magnesium is a metal and magnesium oxide is basic in nature. Copper is the metal which does not react with acids. CO doesn’t produce a salt when reacted with an acid or a base. Some oxides can react directly with water to form an acidic, basic, or amphoteric solution. Have questions or comments? When a metal reacts with oxygen, a metal oxide forms. When they react with an acid, they produce salt and water, showing basic properties. Metal oxides, peroxides, and superoxides dissolve in water actually react with water to form basic solutions. Metal and non-metal oxides. The individual element must be in its highest possible oxidation state because the trend does not follow if all oxidation states are included. a. metal hydroxides b. metal hydrides c. hydrogen gas d. water and a salt Oxides: Group 1 metals react rapidly with oxygen to produce several different ionic oxides, usually in the form of \( M_2O \). 18. shailendrachoubay456 shailendrachoubay456 Answer: (b) Basic in nature. Metals react with oxygen to form their oxides which are generally (a) Neutral in nature (b) Basic in nature (c) Acidic in nature (d) None of these 2 See answers gudiyakumari gudiyakumari Answer: Basic in nature form their oxides which are generally. Metals form basic oxides whereas non-metals form acidic or neutral oxides. \[ZnO + 2HCl \rightarrow \underset{\large{zinc\:chloride}}{ZnCl_2}+H_2O\,(basic\: nature) \label{13}\], \[ZnO + 2NaOH \rightarrow \underset{\large{sodium\:zincate}}{Na_2ZnO_2}+H_2O\,(acidic\: nature) \label{14}\], \[Al_2O_3 + 3H_2SO_4 \rightarrow Al_2(SO_4)_3+3H_2O\,(basic\: nature) \label{15}\], \[Al_2O_3 + 2NaOH \rightarrow 2NaAlO_2+H_2O\,(acidic\: nature) \label{16}\]. Most nonmetal oxides are acidic and form oxyacids, which in turn yield hydronium ions (H 3 O +) in aqueous solution. Nonmetallic oxides react with water to form acids.
