hello aspirant,

"Basic oxides" is a compounds word of "Basic" and "oxides". The word oxides  referred to the chemical compounds that one or more oxygen atoms combined with another element such as h2o  or co2. Based on their acid-base characteristics oxides can be classified into four categories: acidic oxides, basic oxides, and amphoteric oxides and neutral oxides.

Basic oxides, can also called base anhydrides which means "a base without water", are usually formed by reacting of oxygen with metals, especially alkali  (+1 oxidation state) and alkaline earth  metals (+2 oxidation state). Both of them are ionic oxide and can dissolve in water to form basic solutions of the metal hydroxide  whereas non-metals usually form acidic oxides  ter. In general, basicity of . Basic oxide Li2o becomes base LiOH and BaO becomes Ba(OH)2 after react with watheir oxides increases when the elements located downward at the left side of a periodic table (group 1 & 2), as the element become more metallic.

hope this helps,

thankyou.
