What are the most basic oxides?

  • Na2O is the most basic oxide.
  • Al2O3 is amphoteric.
  • P2O5 is acidic oxide.
  • SiO2 is weakly acidic oxide. Hence, the option (D) is correct answer.

Is CaO a basic oxide?

The calcium oxides when reacting with the water form a strong base. Therefore, Calcium oxide is a base.

Is MGO basic oxide?

Hence, magnesium oxide is basic in nature.

Is so2 a basic oxide?

SO2 combines with water to give H2SO3, an acid. So it is an acidic oxide.

Is CO2 a basic oxide?

Carbon dioxide is basic in nature.

Is sio2 a basic oxide?

Silicon dioxide is an acidic oxide. It will react with strong bases to form silicate salts.

Is SO3 basic oxide?

SO(3) is an acidic oxide while Na(2)O is basic in nature.

Is no2 basic oxide?

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.

Is ZnO basic or acidic?

Even though Zinc oxide is a metal oxide, it is not a basic oxide. Because it is an amphoteric oxide, it shows the properties of both acid and base. ZnO ( s ) Zinc oxide + 2 HCl ( aq ) Hydrochloric acid → ZnCl 2 ( s ) Zinc chloride + H 2 O ( l ) Water (Basic nature)

Is CaO a strong acid or base?

CaO is a strong base because it fully dissociates to give ions in solution.

Is CaO acidic?

Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature.

Does calcium form basic oxide?

Hence, Calcium (Ca) yields a basic oxide.

Is CaO amphoteric?

Complete answer:

Calcium oxide is not an amphoteric oxide rather $CaO$ is a basic oxide and when it reacts with acid, salt and water are produced.

Is so2 basic or acidic?

acidic gas
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.

Is na2o basic or acidic?

Sodium Oxide

It is basic because it contains the oxide ion, O2–, which is a very strong base with a high tendency to combine with hydrogen ions. Reaction with water: Sodium oxide reacts exothermically with cold water to produce sodium hydroxide solution. A concentrated solution of sodium oxide in water will have pH 14.

Is o2 basic or acidic?

Oxygen is neither acidic nor basic . It is neutral.

Is SO3 basic oxide?

SO(3) is an acidic oxide while Na(2)O is basic in nature.

Is NO2 basic oxide?

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.
