Which oxide is acidic in group 15?
Which oxide is acidic in group 15?
Solution : All the oxides of nitrogen (expect NO and `N_(2)O “neutral oxides”)` and phosphorus are strongly acidic in nature , oxides of arsenic are weakly acidicl oxides of antimony are amphoteric and those of bismuth are weakly basic.
Which oxide of group 15 is amphoteric?
Sb2O3 is amphoteric; Bi2O3 is basic.
Why are oxides of group 15 acidic in nature?
Acidic character of oxides of group 15 elements decreases and basicity increases down the group. As we move down the group, the atomic size increases, electronegativity decreases and metallic character increases. All these elements form two types of oxides: E2O3 and E2O5.
Is an oxide which is amphoteric?
Amphoteric oxides are classified as metal oxides that react with both acids as well as bases to create salts and water. Amphoteric oxides, among many others, include lead oxide and zinc oxide. Amphiprotic molecules, which can either donate or accept a proton (H+), are one sort of amphoteric species.
Which oxide is the most acidic?
∴P2O5 is most acidic.
Which of the following oxides is amphoteric in nature?
SnO2 shows both acidic and basic properties ∴ it is amphoteric in nature.
Is zno amphoteric oxide?
Zinc oxide is amphoteric because it reacts with both acids and bases to form salts.
Is tio2 amphoteric oxide?
Studies undertaken by a number of workers have shown that hydrous titanium oxide has ion exchange characteristics that are highly dependent on preparative conditions[7–8], and that the titania surface displayed amphoteric characteristics [9–10].
Why the oxides of group 15 elements with higher oxidation state are more acidic?
An atom becomes more electronegative as the oxidation number increases. In this case, the chlorine atom draws electrons from the oxygen atoms that surround it. This then causes the oxygen atoms to become more electronegative. The O-H bond then becomes more polar and therefore more acidic.
What are the trends of oxide of group 15 when we moves down in a group?
The elements of group 15 generally exhibit -3, +3 and +5 oxidation states. The tendency to exhibit -3 oxidation state decreases as we move down the group due to an increase in the size of the atom and the metallic character.
Which is an amphoteric oxide a ZnO B CaO C Bao D SRO?
Amphoteric Oxide: For example: Aluminium oxide is an amphoteric oxide. In the above reaction, aluminium oxide shows acidic character. In the above reaction, aluminium oxide shows basic character.
Which metals form amphoteric oxides?
Two metals which form amphoteric oxides are Zinc and Aluminium. Zinc forms zinc oxide (ZnO) which reacts both with acids and with bases.
