Which of the following oxides is basic in nature?
b) MgO is most basic in nature..
Is b2o3 basic oxide?
No, boron is a nonmetal and its simplest oxide,B2O3, is exclusively an acidic oxide.
What do you mean by basic oxide?
Basic oxides are oxides that show basic properties in opposition to acidic oxides and that either. reacts with water to form a base; or. reacts with an acid to form a salt and water which called neutralization reactions.
What are examples of oxides?

Which of the following is weakest basic oxide?
Electropositive character increases from right to left across the periodic table and increases down the column. So, Sodium appearing to be well place above than the other elements forms the least basic oxide. Answer: Na, due to less metallic property.
Is magnesium oxide acidic or basic?
Depending on its concentration, this will have a pH around 14. As a strong base, sodium oxide also reacts with acids. For example, it would react with dilute hydrochloric acid to produce sodium chloride solution. Magnesium oxide is again a simple basic oxide, because it also contains oxide ions.
Is b2o3 acidic or basic?
b2o3 is an anhydride(when reacted with water, it becomes boric acid) of boric acid I.e., b(oh)3 or h3bo3. Hence, it is said to be acidic.
Is Al2O3 acidic or basic?
Al2O3 is an amphoteric oxide. This means it can behave both as a base as well as an acid.
Is CrO3 acidic or basic?
The oxide CrO3 has an acidic centre Cr(6+) which can be attacked by a nucleophilic group. this is how CrO3 carries out the oxidation of an alcohol to an aldehyde or carboxylic acid. Thus CrO3 is acidic in nature.

Which is most basic in nature?
Basicity of amines depends upon the availability of lone pair of nitrogen for donation. Electron mreleasing group like -CH3 increases the basicity of amines by increasing electron density over nitrogen, which facilitate the donation of lone pair of electrons. Thus, (CH3)2NH is most basic.
Which of the following can produce basic oxide?
Sodium and magnesium metal reacts with the oxygen of the air at room temperature to form sodium oxide and magnesium oxide respectively. These oxides react with water to form hydroxides.
Which is most basic in character?
Answer: 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.
Why is magnesium oxide basic?
Magnesium oxide (MgO) is a base and not an acid. Magnesium is a metal and like most of the metals, it form basic oxides. When magnesium oxide reacts with water the following reaction takes place: … Since magnesium oxide accepts protons (H^+ ions), it is a base (as per Bronsted-Lowry definition of acids and bases).
Is magnesium oxide a gas?
It is hygroscopic, so it will form a solution with moisture in the air if not protected from ambient moisture. Magnesium Oxide (MgO) is a solid and it is typically a powder, in it’s natural state on Earth. It melts at 1,202 degrees Fahrenheit, at which point it is a liquid.
Is cr2o3 acidic or basic?
Chromium(III) oxide is amphoteric. Although insoluble in water, it dissolves in acid to produce hydrated chromium ions, [Cr(H2O)6]3+ which react with base to give salts of [Cr(OH)6]3−.
Is PbO2 acidic or basic?
– Lead oxide (PbO2) is amphoteric oxide and thus reacts with both acids and bases. – PbO2 reacts with HCl to form PbCl2 and H2O.
Is CaO more basic than MgO?
Both calcium and magnesium are alkaline earth metals which belong to 2nd group of the long form periodic table. Their atomic numbers are Mg = 12 and Ca = 20. … Moreover, more is the metallic nature of the element, higher will be the basic nature of its oxide and hydroxide. Thus, CaO is more basic than MgO.
What is magnesium oxide used for?
Magnesium oxide may be used for different reasons. Some people use it as an antacid to relieve heartburn, sour stomach, or acid indigestion. Magnesium oxide also may be used as a laxative for short-term, rapid emptying of the bowel (before surgery, for example).
Which oxide is most basic?
Most basic oxides are ionic in nature base on the difference of electronegativity of oxygen and metals. Dissolving basic oxide in water can increase pH (basicity) of water because basic oxides release hydroxide ions (OH−) to the water.
