(iv) Change in temperature: The chemical reaction between quick lime water to form slaked lime is characterized by a change in temperature (which is a rise in temperature). There are some chemical reactions which can show more than one characteristics.
(iii) Change in state of substance: The combustion reaction of candle wax is characterised by a change in state from solid to liquid and gas (because the wax is a solid, water formed by the combustion of wax is a liquid at room temperature whereas, carbon dioxide produced by the combustion of wax is a gas). The chemical reaction between sulphur dioxide gas and acidified potassium dichromate solution is characterized by a change in colour from orange to green. (ii) Change in Colour: The chemical reaction between citric acid and purple coloured potassium permanganate solution is characterised by a change in colour from purple to colourless. (i) Evolution of gas: The chemical reaction between zinc and dilute sulphuric acid is characterised by the evolution of hydrogen gas. Product: New substance formed after a chemical reaction is called a product. Reactant: Substances which take part in a chemical reaction are called reactants. This is done to remove the protective layer of basic magnesium carbonate from the surface of the magnesium ribbon.
The new substances produced as a result of a chemical reaction are called products.Įxample: The burning of magnesium in the air to form magnesium oxide is an example of a chemical reaction.ĢMg(s) + O 2(g) \(\underrightarrow \) 2MgO(s)īefore burning in air, the magnesium ribbon is cleaned by rubbing with sandpaper. The substances which take part in a chemical reaction are called reactants. Only a rearrangement of atoms takes place in a chemical reaction. In a chemical reaction, a new substance is formed which is completely different in properties from the original substance, so in a chemical reaction, a chemical change takes place. For example: Rusting of iron, the setting of milk into curd, digestion of food, respiration, etc. What is a chemical reaction Class 10?Ĭhemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction.
