After some time, a layer of metal Y from the salt solution is formed on the surface of metal strip X. you get an insoluble yellow compound known as lead (II) iodide and a solution of saltpeter (potassium nitrate). Rancidity is the term used to indicate the development of unpleasant smell and taste in fat and oil containing food due to aerial oxidation and it can be prevented by closely and tight packing of food items in a container which does not allows air to react. 51. Barium chloride solution reacts with sodium sulphate solution to give insoluble barium sulphate and a solution of sodium chloride. Anti-oxidants are used as preservatives in fat containing foods to slow up the development of rancidity due to oxidation. Natural Anti-oxidants are ascorbic acid ad tocopherols whereas synthetic anti-oxidants include Butylated hydroxyanisole (BHA) and Butylated hydroxytoluene (BHT). The result is the dissolve of the lead nitrate. Your IP: 68.66.226.83 (d) Write chemical equation of the reaction which takes place on adding water to solid X. Which of the following can be decomposed by the action of light? What type of reaction is represented by the digestion of food in our body? When calcium oxide reacts vigorously with water to produce calcium hydroxide a large amount of heat is evolved and thus temperature of the system increases hence it confirms that a chemical reaction has been taken place. Nitroglycerine and dynamite. (e) Give one example of another reaction which is of the same type as the above reaction. Lead Nitrate is an inorganic compound which appears as a colorless crystal or white powder. I have a 1993 penny it appears to be half copper half zink is this possible? What is the hink-pink for blue green moray? When an aqueous solution of XNO3 is added to common salt solution, then a white precipitate of compound Y is formed alongwith sodium nitrate solution. The results of this process are two new compounds. Disclaimer | 28. Copper (II) chloride and aluminum?
