mole to relationship between copper and silver

View Lab Report - Mole to Mole Relationship between Cu and Ag(1).pdf from CHM C at Write the equation for the reaction between copper and silver ion. Lab #6 Mole-to-Mole Relationships in a Chemical Reaction The objective will be to determine the mole ratio between silver and copper in the reaction. Once the mole ratio is determined, it may be converted to a whole number ratio, and. From the moles of each substance, determine the ratio of moles between the copper and silver. Use mole relationships to write experimental balanced equation.

Calculate how much copper wire was actually used in the reaction. Record this in the data table above. Collect the blue solution in the mL beaker located underneath the funnel. Use your distilled water bottle to rinse out any particles of silver that may have been left behind in the test tube.

Forming Silver Lab

Wash the test tube thoroughly with distilled water. Your goal is to obtain as much silver as possible. You do not want to leave any behind in the test tube. Is there any silver still in the solution?

If so, you will have to repeat the filtration process making sure to obtain all silver onto the filter paper. Obtain a clean, dry mL beaker. Determine the mass of this mL beaker to the nearest 0. Material Beaker Mass Remove the filter paper cone with the silver and place it into this clean, dry beaker. Place your beaker with the filter paper cone and silver in the tray designated for your class period.

It should be dry when you return to the laboratory the next day. Procedure - Day 3 1. Retrieve your beaker with the filter paper cone containing your dried silver. Determine the mass of the beaker with the filter paper cone containing your dried silver to the nearest 0.

Calculate how much silver you formed in this reaction and record this in the data table below.

Material Silver Mass 4. Return the silver to your teacher for reclaiming. She is going to melt it down and make herself earrings!!!

Write the initial mass of the silver nitrate, AgNO3 used to begin the reaction: What is the molar mass ofAgNO3? Use the initial mass of the silver nitrate in question 5 as the given to calculate the number of moles of silver nitrate, AgNO3, that reacted. Record this number in the data table below. Write the mass of the silver formed: What is the molar mass of silver? Use the mass of the silver formed in question 7 as the given to calculate the number of moles of silver that reacted.

Determine the mass and moles of the copper wire that reacted. Determine the mass and moles of the silver crystals that were produced.

mole to relationship between copper and silver

Find the ratio of moles of silver to moles of copper and round off to the nearest whole number. Write a balanced equation for the single replacement reaction for copper metal with silver nitrate solution. Examine the coefficient s for the copper and silver in the balanced equations. How does the ratio of copper used in the equation to silver produced compare to your mole ratio from the lab?

What is the ratio of moles of silver nitrate used to moles of silver produced?

mole to relationship between copper and silver

Is the mole ratio of moles of silver nitrate to silver moles the same as in the balanced equations? How many atoms of silver were produced in your lab? How many atoms of copper reacted?

mole to relationship between copper and silver

What is the ratio of the two? How does this compare to the ratio from the balanced equation? Write a formal conclusion.

Experiment #4 Mole Relationships In A Chemical Reaction

Silver nitrate will stain skin and clothes if it contacts them. Once the wire stops reacting, nearly all of the silver has been chemically converted from aqueous silver ion to silver metal. Silver metal does not react with skin. What would happen if an equal length of very fine copper wire were used in this experiment?

A fine copper wire might not provide enough copper metal to react with all of the silver. In this event, all of the wire in the solution would dissolve, and some silver ions would remain dissolved in the solution. Find the number of moles of silver produced.

Forming Silver Lab

Find the number of moles of copper consumed during the reaction. Find the mole ratio of copper to silver in this reaction round to the nearest whole number.

mole to relationship between copper and silver

Write a balanced equation for the reaction using the mole ratio derived above as the coefficients. During the middle ages, a group of people called alchemists searched unsuccessfully for a way to "transmute" or change one element to another, e. Was the copper "transmuted" into silver in this experiment?

Calculate the moles of silver nitrate in the original solution. What percentage of this was changed to silver?

Find the number of atoms of copper removed from the wire. How would the calculated mole ratio be affected if the silver were not completely dry when weighed? List any other errors that could have affected your results.
