A.CaOCaO
B.SiO2Si{O_2}
C.CO2C{O_2}
D.SnO2Sn{O_2}
D.Solution:

Explanation

Solution

In the given question firstly we have to define what exactly are the amphoteric oxides and then what they are made of and then the main outline of it and give the proper definition and the characteristics of it. And now we can also say that they are Metal dioxides are the ones which react with both the compounds that are acids as well as bases.

Complete answer:
The given question statement asks about the amphoteric oxides. We have to provide the basic definition and the other important characteristics for these along with the significance in chemistry.
The Metal dioxides are the ones which react with both the compounds that are acids as well as bases to produce salts and water are known as amphoteric oxides. Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides.
The dioxide of SnO2Sn{O_2} reacts with the acid as well as the bases. So we can easily say that the SnO2Sn{O_2} is an amphoteric oxide. Now the CaOCaO is the ones basic in nature, while SiO2Si{O_2} and CO2C{O_2} are acidic in nature.
The Amphoteric oxides are the ones that can be defined as oxides that can behave as an acid and a base to produce salt and water.
Amphoterism depends on the oxidation states available to a chemical species.

Note:
Amphoteric is derived from the Greek word amphoteroi meaning "both". Related words in acid-base chemistry are amphi chromatic and amphiprotic, both describing substances such as acid-base indicators which give one colour on reaction with an acid and another colour on reaction with a base.
