What amphoteric called?
In chemistry, an amphoteric compound is a molecule or ion that can react both as an acid and as a base. What exactly this can mean depends on which definitions of acids and bases are being used. The prefix of the word ‘amphoteric’ is derived from a Greek prefix amphi which means “both”.
What does amphoteric mean in terms of water?
A species that has the potential to act both as an acid and as a base according to Brønsted-Lowry Theory is said to be amphoteric. Since water has the potential to act both as an acid and as a base, water is amphoteric.
What is the difference between anhydrous and anhydride?
Anhydrous materials differ from anhydrides. Anhydrides react irreversibly with the oxygen-hydrogen bonds of water to form new compounds whereas anhydrous compounds simply form reversible adducts with water molecules. The hydrated forms of the compounds shown below can be converted into the anhydrous forms by heating.
Which pair is amphoteric?
Both Be(OH)2 and Zn(OH)2 are amphoteric in nature.
What are atmospheric oxide give two example of atmospheric oxide?
Examples of amphoteric oxides are zinc oxide and aluminium oxide.
Is HSO4 amphoteric?
The hydrogen sulfate ion HSO4- is amphoteric.
What is meant by the term amphoteric give an example?
An amphoteric compound is one that can react with both acids and bases. The word amphoteric comes from Greek, where Ampho means both or both kinds – i.e. amphoteric compounds can react with both acids and bases.
What is meant by the term amphoteric give an example of a substance that has amphoteric characteristics?
In chemistry, an amphoteric substance is a substance that has the ability to act either as an acid or a base. However, if water comes in contact with an acid, like hydrochloric acid, it will act as a base by receiving a proton in the form of a hydrogen ion from the hydrochloric acid.
What is the difference between hydrous and anhydrous?
Hydrous compounds are chemical compounds that are composed of water molecules in their structure as a constituent. Anhydrous compounds are chemical compounds that have no water molecules in the chemical structure. This is the main difference between hydrous and anhydrous compounds.
What is the opposite of anhydrous?
Definition: without water; especially without water of crystallization. Antonyms: hydrated, hydrous.
Which of the following pair is amphoteric in nature and why?
Solution: BeO and ZnO are amphoteric in nature because they can react both in acidic as well as a basic solution.
