Chemical Reactions and Equations

Activity1.1: Burning of Magnesium

Description: Magnesium Burns in Air(Oxygen) to form Magnesium Oxide.

Activity1.2: Reaction: Lead Nitrate and Potassium Iodide

Description: When a solution of lead nitrate is poured into a solution of Potassium iodide a yellow precipitate of lead iodide is formed.

Activity1.3: Reaction: Zinc and Sulfuric Acid

Description: Concentrated sulfuric acid reacts vigorously with zinc. The gas evolved is hydrogen from this highly exothermic reaction.

Activity1.4: Reaction: Calcium Oxide and Water

Description:This experiment serves to demonstrate the exothermic chemical reaction between water (H20) and calcium oxide (CaO).

Activity1.5: Reaction: Decomposition of Iron Sulphate

Description: Iron sulphate decomposes into ironoxide and sulphur oxides

Activity1.6: Reaction: Decomposition of Lead Nitrate

Description: Lead Nitrate decomposes into lead oxide releasing NO2 gas

Activity1.7: Electrolysis of water

Description: Water dissociates into Hydrogen and Oxygen gas.

Activity1.8: Reaction: Decomposition of Silver Chloride in sunlight

Description: Silver chloride decomposes into silver and chlorine gas, a method used in earlier photography.

Activity1.9: Reaction: Iron with Copper Sulphate

Description: Iron being more reactive displaces copper to form iron-sulphate. Copper gets deposited on iron nails.

Activity1.10:Reaction:Sodium sulphate and barium chloride

Description: Barium sulphate forms as white precipitate.

Activity1.11:Heating Copper in air

Description: Surface of copper oxidizes forming copper oxide.

That's all in chapter 1. Do post your comments and suggestions.

Quite long ago, when I was in high-school, Math and science used to be my favorite subject. Obviously, they are still my favorites but things have quite narrowed down. While I look back on what could have made others also interested in Maths and Science, I feel it's visualization of the subject. When students study social-science subjects, they can relate to the concepts taught in the class but for science and maths, it becomes really difficult.

This is an attempt to bring some visualization in science classes through an extremely simple steps. Science books from high schools contain numerous "activities" to introduce new concepts in science. For most of these activities, it is easy to find related youtube videos. I am just organizing these videos and posting it in organized ways. Hope this helps!

Do watch and share. I would also request to have your comments that can improve this blog. Also, if you want to collaborate, just let me know @ deepoo.iitb@gmail.com
