Single Displacement Reaction The objective of this experiment was to observe evidence of a reaction and to determine the chemical equation, if there is a reaction. In order for a reaction to occur, a metal strip must have evidence of black or grey deposits on the surface of the metal once dipped into the solution. The reactivity of an element is related to its tendency to lose or gain electrons. Three metal strips that were used are copper, lead and zinc as well as the solutions of silver nitrate, copper(II) nitrate, lead(II) nitrate, magnesium sulfate and dilute(3M) sulfuric acid. The copper metal strip was placed in the silver nitrate and dilute(3M) sulfuric acid, the lead metal strip was placed in the copper(II) nitrate and the zinc metal strip was placed in the lead(II) nitrate, magnesium sulfate and dilute(3M) sulfuric acid. Overall, putting these different strips of metal into different solutions will help determine the reactivity of copper, lead, zinc, magnesium, silver and hydrogen.…
- The food coloring + CH3COOH darkening in color, food coloring + NaOCI + CH3COOH returning to clear, red cabbage + NH3 turning green, red cabbage + CH3COOH turning pink, NaHCO3 + CH3COOH bubbling over, Na2CO3 + CH3COOH fizzing and turning cloudy, MgSO4 + NH3 turning white, and the MgSO4 + Na2CO3 becoming thick are all examples of macroscopic evidence for chemical change.…
Ans: We can experimentally let the light to pass through a prism which will allow us to see whether copper solution is blue, green or both colors as the prism will be able to separate the two colors as they bend differently according to their wavelengths .If it’s one color we will see it after passing through the prism and if it’s both colors will know the which one of them has…
In this lab, we changed copper into various forms using different chemicals and chemical reactions. The purpose of this lab is to demonstrate that the product of a chemical reaction depends on what is present at the time of that reaction. This lab also displays how matter cannot be created nor destroyed in a chemical reaction.…

Rocks containing copper compounds (such as copper carbonate) are called ‘copper ore’. Copper is extracted from copper ore by a series of chemical, physical, and electrochemical processes. Ores can be classed as ‘high grade’ or ‘low grade’ depending on the percentage of copper compounds (e.g. copper carbonate) they contain.…

Chemical Reaction of copper compounds Introduction: In this experiment, the objective was to conduct a series of chemical reactions that contain copper or copper compounds. That is to say that the products of each chemical reaction were used in the next reaction. The process starts with a solid copper wire dissolved in nitric acid and the end product is copper powder. The product which was used from the previous reaction is the limiting. In the initial step, the solid copper is the limiting reactant. For this experiment, the materials that will be used are copper wire, aluminum wire, six molar nitric acid, sodium hydroxide, six molar hydrochloric acid, a vacuum filtration apparatus, and ice.…
