Types of Reactions and Examples of Inorganic compounds

There are about four types of chemical reactions in Inorganic chemistry namely combination, decomposition, single displacement and double displacement reactions.

• Combination Reactions: As it is in the name ‘Combination’, here two or more substances combine to form a product which is called a Combination reaction. For example: Barium + F₂ → BaF₂
• Decomposition Reaction: It is a type of reaction where a single element splits up or decomposes into two products. For example: FeS → Fe + S
• Single Displacement Reactions: A reaction where a single atom of one element replaces another atom of one more element. For example: Zn (s) + CuSO₄ (aq) → Cu (s) + ZnSO₄ (aq)
• Double Displacement Reactions: This type of reaction is also called ‘metathesis reactions’. Here two elements of two different compounds displace each other to form two new compounds. For example:CaCl₂ (aq) + 2AgNO₃ (aq) → Ca(NO₃)₂ (aq) + 2 AgCl (s)
