Silver and Test Tube
Copper- propertyy treat Reaction Introduction In this look into sloven wire get discover be placed in a solvent of property nitrate. This individual(a) replacement response will produce a bluing solution of copper II nitrate and unwavering smooth. By weighing the reactants in advance the reaction, the mass of money produced can be predicted. This theoretical yield can be compared to the actual yield of silver. Purpose Students will compare the theoretical mass of silver with the actual mass of silver from the single replacement reaction between copper and silver nitrate.Materials Copper wire intake rod 18 x one hundred fifty mm assay tube silver nitrate, AgN0350 mL graduated cylinder distilled irrigate 100 mL or 250 mL beaker Procedure day 1 1 . Obtain a 30 cm length of bare copper wire, stir rod, and 18 x 150 mm test tube. coll the copper wire by wrapping It around a glass-stirring rod. demoralize the spiral wire until It Is about 2 cm longer than the test tub e. submit wire tightly coiled shape up one end and stretched out and groom toward the other Weigh the wire and present it in the selective information table to the close 0. 01 grams. using weigh paper, weigh out about 1. 5 g of silver nitrate, AgN03. Record the measurement in data table to the nearest 0. 01 grams. (Caution Be heedful not to get any of the silver nitrate, solution or solid, on your bark or clothing. It will react with them. ) 3. visor about 20 mL of distilled pissing In a graduated cylinder and pour It Into the test tube. Add the solid silver nitrate tothe water In the test tube. 4 Carefully consort the stlrrlng rod up and down to split up the crystals and mix the solution, Take great manage not to poke a holeIn the crumb of the test tube with the stirring rod. disinfect the stirring rod with a minute amount ot distilled water into the test tube. institutionalise the coiled wire in the silver nitrate solution with the closely coiled end at the bottom of the test tube. instal the test tube into a beaker. 6. Record observations during the next 15 minutes. 7. Set your labeled beaker in the designated area, allowing it to react overnight. Day 2 8. Weigh the 100 mL beaker. 9. Shake the crystals from the copper wire. using a wash bottle, rinse the wire Into he weighed 100 mL beaker. et the wire deflection to dry. weigh the copper wire when
