QUESTION:-

Complete the paragraph given below with the help of options given in brackets:

Bracket= (increases, decreases, remains same, FeO, Fe2O3, Fe3O4, FeO2)

ANSWER

When the positive charge on an atom or an ion increases or the negative charge on them decreases it is called as oxidation.

When the positive charge on an atom or an ion decreases or the negative charge on the them increases then it is called as reduction.

EXPLANATION:-

• Oxidation is the loss of electrons
• Reduction is the gain of electrons.
• When electrons are gained in an atom or an ion their positive charge decreases.
• When there is a loss of electrons the negative charge decreases.
• The answer to the first blank is increased because in oxidation there is a loss of electrons which increases the positive charge of an atom or an ion.
• The answer to the second blank is decreases because, in oxidation, the loss of electrons reduces the negative charge of an atom of an ion.
• The answer of the third blank is decreases because in reduction there is a gain of electrons which reduces the positive charge of the atom or an ion.
• The answer of the fourth blank is increases because in reduction electrons are gained which increases the negative charge of the atom or an ion.
