S. CISCE ICSE Class 9.

Shut off burner when finished!!!

When the copper sulfate is heated up, it quickly turns to a pure white color that has no hint of blue in it. Copper(II) nitrate crystals will began to bubble and melt veryquickly. Anhydrous copper nitrate forms deep blue-green crystals and sublimes in a vacuum at 150-200 °C. Silver Nitrate is commonly known as Lunar caustic. Copper nitrate also occurs as five different hydrates, the most common ones being the trihydrate and hexahydrate.These materials are more commonly encountered in commerce than in the laboratory. When heated, copper is easily bent or molded into shapes. Answer. + cobalt Nitrate Solution in a watch glass and burnt 6. Copper is a reddish-brown metal, widely used in plumbing and electrical wiring; it is perhaps most familiar to people in the United States in the form of the penny. Copper nitrate is a blue coloured crystal. Actually, the nitrate ion oxidizes the copper metal to copper (II) ion while itself being transformed to NO 2 gas in the process; the copper (II) ion then binds to six water molecules.

(ii) When the gaseous product obtained by dehydration of ethyl alcohol is passed through bromine water. When copper nitrate is heated it loses the water molecule and then when is further heated it decomposes to give reddish brown gas, nitrogen dioxide and oxygen. Concept: Characteristics of Chemical Reactions. State the observation: 1 when crystals of copper sulphate are heated in a test tube 2 Ammonium sulphate is heated with NaOH and the gas liberated is bubble into methyl orange soln 3 Ammonia gas is passed through copper nitrate solution - Chemistry - Study of Compounds Question Papers 10. State one relevant observation "when crystals of copper nitrate are heated in a test tube." Action of hot and concentrated Nitric acid on copper. HCl is added to lead nitrate solution and heated, it forms a white precipitate of lead chloride.
