As…. Acid+Base= Salt +waterStrong Acid + Weak Base = Acidic SaltWeak Acid + Strong Base = Basic Salt
Basic oxide:Metals react with oxygen to give basic compounds of oxygen. These compounds are usually ionic in nature. Group 1, 2 and lanthanides form basic compounds of oxygen when they react with dioxygen. During the formation of these compounds, a large amount of energy is released. These compounds readily react with water except a few exceptions.Examples: M2O3, MO2, ThO2Na2O + H2O → 2NaOHAcidic oxide:Non-metals react with oxygen to form acidic compounds of oxides which are held together by covalent bonds. These compounds can also be called as acid anhydrides. Acid anhydrides usually have a low melting and boiling point except for compounds like B2O3\xa0and SiO2\xa0which have high melting points and form giant molecules.Examples: NO, CO2SO3\xa0+ H2O → H2SO4B2O3\xa0+ H2O → 2H3BO3
1. Basic oxide is metalic oxide whereas Acidic oxide is Non metallic oxide 2.Solution of basic oxide changes colour of red litmus to blue whereas solution af acidic oxide changes colour of blue litmus to red.
