Neutral oxides show neither basic nor acidic properties and hence do not form salts when reacted with acids or bases, e.g., carbon monoxide (CO); nitrous oxide (N2O); nitric oxide (NO), etc., are neutral oxides. water and a salt. Superoxides: Often Potassium, Rubidium, and Cesium react with excess oxygen to produce the superoxide, $$MO_2$$. Performance & security by Cloudflare, Please complete the security check to access. They react with acids to produce salts, e.g., $\ce{ MgO + 2HCl \rightarrow MgCl_2 + H_2O } \label{9}$, $\ce{ Na_2O + H_2SO_4 \rightarrow Na_2SO_4 + H_2O} \label{10}$. Non-metal oxides on the right side of the periodic table produce acidic solutions (e.g. These metallic oxides are known as basic anhydrides. The oxide that gives a base in water is known as a basic oxide. Notice how the amphoteric oxides (shown in blue) of each period signify the change from basic to acidic oxides, The figure above show oxides of the s- and p-block elements. Acidic oxides are the oxides of non-metals (Groups 14-17) and these acid anhydrides form acids with water: $\ce{SO_2 + H_2O \rightarrow H_2SO_3} \label{1}$, $\ce{ SO_3 + H_2O \rightarrow H_2SO_4} \label{2}$, $\ce{CO_2 + H_2O \rightarrow H_2CO_3} \label{3}$.

An amphoteric solution is a substance that can chemically react as either acid or base. Most metals form oxides with the oxygen in a -2 oxidation state. Metal oxides, peroxides, and superoxides dissolve in water actually react with water to form basic solutions. with the oxidation number of the oxygen equal to -1. Oxygen can thus be obtained from acidified water by its electrolysis. $4 Li + O_2 \rightarrow 2Li_2O \label{19}$ Peroxides: Often Lithium and Sodium reacts with excess oxygen to produce the peroxide, $$M_2O_2$$. Examples of Oxides (Group 1 elements react with oxygen): Lithium reacts with oxygen to give oxide. Cl2O, SO2, P4O10). It is important to remember that the trend only applies for oxides in their highest oxidation states. Most nonmetal oxides are acidic and form oxyacids, which in turn yield hydronium ions (H 3 O +) in aqueous solution. They are oxides of either nonmetals or of metals in high oxidation states.Their chemistry can be systematically understood by taking an oxoacid and removing water from it, until only an oxide remains. By direct heating of an element with oxygen: Many metals and non-metals burn rapidly when heated in oxygen or air, producing their oxides, e.g., $P_4 + 5O_2 \xrightarrow{Heat} 2P_2O_5$.

It may also help to examine the physical properties of oxides, but it is not necessary. Lets start with reaction of metals with oxygen. There is a trend within acid-base behavior: basic oxides are present on the left side of the period and acidic oxides are found on the right side. These oxides, however, do not give hydrogen peroxide by action with dilute acids. Substances that are not reactive are called unreactive or inert. Yes, an example is carbon monoxide (CO). Non-metals react with oxygen to form acidic compounds of oxides which are held together by covalent bonds. Acidic Oxides. Example: SO3 + H2O → H2SO4 Basic Oxide. Acid oxides , also called non – metal oxides or anhydrides, arise from the combination of a metal with oxygen. Acid anhydrides usually have a low melting and boiling point except for compounds like B 2 O 3 and SiO 2 which have high melting points and form giant molecules. 1. Na2O and MgO). See section above on Properties of Amphoteric Oxides for more detail. If soluble in water, they react with water to produce hydroxides (alkalies) e.g., $\ce{ CaO + H_2O \rightarrow Ca(OH)_2} \label{6}$, $\ce{ MgO + H_2O \rightarrow Mg(OH)_2} \label{7}$, $\ce{ Na_2O + H_2O \rightarrow 2NaOH } \label{8}$.
