Oxides formed by `p`-block elements may be
`(i)` basic
`(ii)` acidic
`(iii)` amphoteric
`(iv)` neutral

Give one example each of acidic, basic, amphoteric and neutral oxides.

Write the main difference between an acid and a base. With the help of suitable examples explain the term neutralization and the formation of- (i) acidic, (ii) basic and (iii) neutral salts.

(a). With the help of examples, describe how metals oxides differ from non-metal oxides. (b). Which of the following elemetns woul yield: (i) an acidic oxide, (ii) a basic oxide, and (iii) a neutral oxide Na, S, C, K, H

The element that forms most basic oxide is :

What is the nature of oxides formed by most of p -block elements?

The binary compounds of oxygen with other elements are called oxides. They are classified depending either upon their acid-base characteristics or on the basis of oxygen content. (a) Normal oxides : These oxides which contain oxygen atom as permitted by the normal oxidation number, i.e., -2 normal oxide may be acidic, basic, amphoteric or neutral. (b) Polyoxides : The oxides which contain oxygen atoms different than those permitted by the normal oxidation number of -2 . (i) Peroxides : Two oxygen atoms are linked to each other and oxyegen has -1 oxidation number. They contain (O -O)^(2-) unit. (ii) Superoxodes : These oxides contain (O-O)^(-1) unit, i.e., each O-atom has oxidation number -1//2 . (c) Suboxides : These contain low content of oxygen than expected. (d) Mixed oxides : These oxides are made of two simpler oxides. Which of the following pairs contains amphoteric oxides ?
