Concept Introduction:
Oxidation number is integer value allotted to every element. It is formal charge occupied by atom if all of its bonds are dissociated heterolytically. Below mentioned are rules to assign oxidation numbers to various elements.
1. Elements present in their free state have zero oxidation number.
2. Oxidation number of hydrogen is generally
3. Oxidation number of oxygen is
4. Metals have positive oxidation numbers.
5. Negative oxidation numbers are assigned to most electronegative element in covalent compounds.
6. Sum of oxidation numbers of different elements in neutral atom is zero.
7. Sum of oxidation numbers of various elements in polyatomic ion is equal to charge present on ion.

- What does it mean for a substance to be oxidized? The term “oxidation” originally came from substances reacting with oxygen gas. Explain why a substance that reacts with oxygen gas will always be oxidized.arrow_forwardDetermine the oxidation number of each element in each of the following compounds: (a) HCN (b) OF2 (c) ASCl3arrow_forward. Balance each of the following half-reactions. a.I(aq)I2(s)b.O2(g)O2(s)c.P4(s)P3(s)d.Cl2(g)Cl(aq)arrow_forward
- Four metals, A, B, C, and D, exhibit the following properties: (a) Only A and C react with 1.0 M hydrochloric acid to give H2(g). (b) When C is added to solutions of the ions of the other metals, metallic B, D, and A are formed. (c) Metal D reduces Bn+ to give metallic B and Dn+. Based on this information, arrange the four metals in order of increasing ability to act as reducing agents.arrow_forwardBalance each of the following oxidationreduction reactions by using the oxidation states method. a. C2H6(g) + O2(g) CO2(g) + H2O(g) b. Mg(s) + HCl(aq) Mg2+(aq) + Cl(aq) + H2(g) c. Co3+ (aq) + Ni(s) Co2+(aq) + Ni2+(aq) d. Zn(s) + H2SO4(aq) ZnSO4(aq) + H2(g)arrow_forward. In each of the following reactions, identify which element is oxidized and which is reduced by assigning oxidation states. a.2Br2O3(s)+6Cl2(g)4BCl3(l)+3O2(g)b.GeH4(g)+O2(g)Ge(s)+2H2O(g)c.C2H4(g)+Cl2(g)C2H4Cl2(l)d.O2(g)+2F2(g)2OF2(g)arrow_forward
