Question

name the confirmatory test used to find out the nature of metal and non-metal oxides​

Answer 1

Explanation:

metal oxide:-

Metal oxides are basic in nature because they react with water to form bases. Moreover, the oxides turn moist red litmus paper blue and blue remains blue.

Non-metal

Non-metallic oxides are formed by the reaction of non-metals with oxygen. They react with a base to give salts and water. Let us consider the Calcium hydroxide (base) reaction with carbon dioxide (non-metallic oxide) to produce salt and water.

Ca(OH)2 + CO2 → CaCO3 + H2O

Sulphur burns in the air to produce sulphur dioxide.

2S + O2 → SO2

Other examples of non-metallic oxides – CO, NO2, Cl2O, XeO4
