Is BaO acidic or basic?
Hydroxide aka (OH) ions are formed, so BaO is a basic oxide.
Rule of thumb: Metals typically form metal oxides.
Substances that react with both acids and bases are classified as amphoteric (469)..
Is p4o10 acidic or basic?
Question: P4O10 Is Classified As An Acidic Oxide Because It A. Reacts With Acids To Produce A Salt.
Is cro3 acidic or basic?
Chromium trioxide (also known as chromium(VI) oxide or chromic anhydride) is an inorganic compound with the formula CrO3. It is the acidic anhydride of chromic acid, and is sometimes marketed under the same name.
Is so2 acidic or basic?
Sulphur dioxide is an acidic gas and this can easily be demonstrated by adding water and a few drops of universal indicator to a container of the gas. The resulting acid is the weakly dibasic acid sulphurous acid (H2SO3).
Which is the most acidic oxide?
Thus, chlorine has the highest oxidation state. Hence, Cl2O7 is the most acidic oxide.
Is Cl2O7 acidic in water?
Na2O reacts with water to form sodium hydroxide [NaOH] which turns red litmus paper blue.So Na2O is a basic oxide. Cl2O7 reacts with water to form perchloric acid [HClO4] that turns blue litmus paper red. So Cl2O7 is an acidic oxide.
Which is more acidic Cl2O7 or n2o5?
When Cl2O7 reacts with water, HClO4 forms. It’s the strongest acid. Therefore Cl2O7 also acidic. HNO3 is strong with pKa HClO4 is the strongest (pKa ~ -10).
What makes something more acidic?
The closer the negative ion is to the H+ ion in the molecule, the stronger the acid is. Look at the strengths in the bonds between the molecules in the ion. The more lopsided it is throughout the molecule, the stronger the acid. A molecule with a triple bond is more acidic than one that only has single bonds.
Which is more acidic SiO2 or co2?
CO2 is more acidic than SiO2 because metallic character increases ans we move down the group. And USUALLY, metals are bases, so, SiO2 would be more basic than CO2 or CO2 is more basic than SiO2.
