With the exception of beryllium oxide, BeO, which is amphoteric, all of the Group I and II metal oxides are strongly basic.
Why is BeO acidic?
Hint: A compound that can react as an acid as well as a base is said to be amphoteric in nature. In this reaction, BeO reacts with a sodium hydroxide base (NaOH) to produce a salt sodium beryllate (Na2BeO2) and water. In this reaction, BeO acts as an acid. It reacts with a base to give salt and water.
Why is beryllium oxide an amphoteric oxide?
Beryllium oxide is amphoteric because it can react with both acidic and basic solutions.
Is zno acidic oxide?
For example, zinc oxide acts as an acidic oxide when it reacts with concentrated sodium hydroxide. However, it acts as a basic oxide while reacting with hydrochloric acid.
Is B2O3 an amphoteric oxide?
On moving down the group, the basicity of the oxide increases along with increase in metallic character of the element. Thus B2O3 is acidic, Al2O3 and Ga2O3 amphoteric while In2O3 and Tl2O3 are basic. Being the oxide of a non-metal it is acidic in nature. It is the anhydride of boric acid.
Which is more acidic in nature?
Therefore, 2-chlorobutanoic acid is the most acidic in nature.
What type of reaction is beryllium oxide?
This is a combination reaction because the Be and O2 come together to form beryllium oxide.
Is ZnO a base or acid?
All Answers (7) Pure ZnO is has basic nature (nanopowder). However if dissolved in ethanol the solution is acid. ZnO is amphoteric, so it can have both acidic or basic behaviour, depending on the media it is placed in... ZnO is amphoteric, so it can have both acidic or basic behavior, depending on the conditions.
Is al2o3 basic or acidic?
Aluminum Oxide Aluminium oxide is amphoteric. It has reactions as both a base and an acid.
Which phenol is more acidic in nature?
Phenol is more acidic than aliphatic compounds containing OH group due to resonance stabilization of phenoxide ion by the aromatic ring. In this way negative charge of oxygen atom is delocalized on ortho and para carbon atoms. Due to which stability increases.
Is CaO acidic in nature?
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.
Is as2o3 acidic or basic?
Arsenic trioxide is an amphoteric oxide, and its aqueous solutions are weakly acidic. Thus, it dissolves readily in alkaline solutions to give arsenites.
What is the pH of beryllium oxide?
2.7 The soluble cationic compounds, when dissolved in water, undergo hydrolysis, resulting in an acidic pH of 2.7 for iso-osmolar beryllium sulfate (Delic, 1992; HSE, 1994). Beryllium shows a high affinity for oxygen in air and water, resulting in a thin surface film of beryllium oxide on the bare metal.
What are the advantages of beryllium?
Beryllium contributes hardness, strength, high electrical and thermal conductivity, and resistance to corrosion, wear, and fatigue. For example, BeCu springs bounce back to their original shape again and again.
