Oxidation state is used to indicate the degeree of oxidation of an atom in chemical compound. Oxidation states are represented by integers, it can be any whole number which doesn’t have fractional part. In simple words oxidation can be defined as, “The combination of a substance with oxygen.” In this article you can find some questions related to oxidation and their answers: Questions: 1. A compound contains atoms X, Y and Z. The oxidation number of X is +3, of Y is +5 and of Z is -2. The possible formula of the compound...

An oxidation number of an atom is a positive or negative number which shows how many electrons an atom has gained, lost, or shared to become stable. Some of the features of Oxidation number are as follows: 1. It is the extent of charge of an atom which is developed in the formation of a compound. 2. It may be positive or negative for an element, E.g. Oxidation number of P in is -3 and +3, respectively. 3. It may be of different value in different compounds for the same element, E.g. Oxidation number of C in are -4, -2, 0, +2 and +4...

The equivalent weight can be defined as the weight of a substance that will combine with or replace one mole of hydrogen or one-half mole of oxygen. Equivalent weight of an element is equal to the atomic weight or formula weight divided by the valence. In this article you can find some questions and their answers related to equivalent weights: Questions: 1. Which of the following oxides is most acidic in nature (a) (b) (c) (d) All are similar acidic in nature 2. Which is the weakest acidic in nature (a) ...

Oxidation is the process of gaining electrons and Reduction is the process of loosing electrons. Those substances which oxidises others and itself undergoes reduction is known as oxidising agent. Oxidising agent can also be called as electron acceptor or oxidant. Those substances which undergoes oxidation but reduces others is known as reducing agent. Reducing agent can also be called as reductant or electron loser. Some question related to oxidation and reduction are given below: Questions: 1. Oxidation involves: (a) Loss of...
