Get PriceJun 11, 2010 · This is due today! Please help! In a student experiment, the empirical formula of a copper halide was found by adding aluminum metal to an aqueous solution of the halide, displacing copper metal. The copper metal was filtered, washed with distilled water, dried, and weighed; three separate determinations were performed. The copper halide solution contained 42.62 g of copper .
Single Displacement Reaction: Zinc and Copper(II) Ion REDOX . When zinc metal is immersed in a solution of 0.1 M aqueous copper(II) sulfate solution c opper metal plates out on the zinc. The solution is initially blue in color. A dark coating of copper metal appears on the zinc within two minutes and when 45 minutes have elapsed, there is a ...
Get PriceSep 30, 2008 · Since the other reaction product is metallic silver precipitate, and everyone knows what silver looks like, the blue is from the copper nitrate by process of elimination. The original solution was not blue because silver nitrate is colorless/slight gray when in solution and Cu(s) is just copper metal.
The order was based on the reactivity demonstrated when strips of the metal were immersed in the solutions. Magnesium reacted with three of the solutions, zinc reacted with two, copper with one and silver did not react with any of the solutions. Metal Ion Table Metal Table Ag+ Ag .
Get Pricecopper metal forms during this period. Vigorous evolution of hydrogen gas is also observed during the addition. After the reaction is complete, add 5 mL of 6M HCl solution and stir the mixture with a glass rod. This process removes any unreacted zinc metal.

First, dip any piece of iron in nitric solution. If reaction starts immediately and you think that your metal is dissolving in solution then add water to the dilute nitric solution.
Get PriceGenerally, when metals are fully reduced, they form elemental metal and "plate" the site where they were reduced. In the first reaction, the copper ion is able to oxidize the zinc metal. However, in the second reaction, the zinc ion is not able to oxidize the copper metal. Zinc is a better reducing agent than copper.
