White Washing Process
Firstly, we have to know the process of white washing. During white washing of our house, mistri take some amount of water in his bucket and put a packet of quicklime in it and shake it. After few seconds, some amount of heat energy produced from the bucket. As we know that if energy needed in the bond breaking in the reactants is less than the energy released when new bonds are formed resulting in the products, the chemical reaction is of exothermic in nature which is known as exothermic reaction. Then calcium hydroxide produced with some amount of heat energy which is a strong base because calcium is more reactive in nature for more reactive metal.
Answers:
The name of the substance is Calcium Oxide or Quick lime. The chemical formula of the substance is CaO(s). The chemical reaction of the substance Calcium Oxide with water:
Reaction: CaO(s) + H2O(l) → Ca(OH)2 (aq) + Heat
The reaction is highly rigorous as well as exothermic in nature. It is accompanied by hissing noise and bubbles produced from the container. The solution initially start boiling. As result of combination reaction between calcium oxide and water, Calcium hydroxide is formed.
