Is CaO more basic than SrO?

Basic strength of alkaline earth oxides is in the order: MgO < CaO < SrO < BaO.

Which of the following oxides is the most basic oxide SrO BaO CaO MgO?

Barium has higher atomic size or radius due to which it has highest reactivity and thus the basic order increases. Therefore \[BaO\] is the most basic oxide.

Which oxide is most basic?

Na2​O is the most basic oxide.

  • Al2​O3​ is amphoteric.
  • P2​O5​ is acidic oxide.
  • SiO2​ is weakly acidic oxide. Hence, the option (D) is correct answer.

    • Which of the following oxides is most basic a Bi2O3 B SeO2 C a12o3 D Sb2O3?

    More the oxidation state of the central atom (metal) more is its acidity. Hence SeO2 (O. S. of Se = +4) is acidic. Further for a given O.S., the basic character of the oxides increases with the increasing size of the central atom. Thus Al2O3 and Sb2O3 are amphoteric and Bi2O3 is basic.

    Is CaO or K2O more basic?

    The decreasing order of basic character of K_(2)O BaO , CaO and MgO is. Alkali metal oxides are more basic than their corresponding alkaline earth metal oxides . Thus , K2O is the most basic .

    Which is the least basic oxide?

    Solution: Lithium monoxide (Li2O) is least basic. On moving down the group in alkali metals, the baicity of oxides increases.

    Is CaO a basic oxide?

    Calcium oxide (CaO) , is a metal oxide. Like other metal oxides it is a basic oxide because it dissolves in water to form calcium hydroxide.

    Which is more basic character?

    CsOH is the most basic in character out of all the given options. Explanation: Basicity of the oxides of elements is related to the metallic properties of the elements.

    Which of the following is most basic oxide so3?

    Oxygen is common in all oxides of group-16, and electronegativity decreases as we down the group thus basic nature of oxide increase. Hence PoO is the most basic oxide.

    Why is Bi2O3 the most basic oxide?

    It is non-metal and forms an acidic oxide. This is because as we go down the group the metallic character increases. So, Bi has increased metallic character. Hence, it forms a basic oxide.
