Chemical Reactions Homework: Copper & Silver Nitrate Reaction

In summary, when copper metal is placed in a beaker containing a solution of silver nitrate, a chemical reaction occurs and can be represented by the equation 2AgNO3(aq) + Cu(s) -----> Cu(NO3)2(aq) + 2Ag(s). The net ionic equation for this reaction is 2Ag+(aq) + Cu(s) -----> Cu2+(aq) + 2Ag(s). Evidence of this reaction can be seen through a color change, as copper and silver have different colors. Copper is typically a reddish-brown color, while silver is a shiny, metallic silver color.

Write ionic form first.

What is copper color? What is silver color?
 
  • #3


it is important to understand and accurately represent chemical reactions. The net ionic equation for this reaction would be:

2Ag+(aq) + Cu(s) -----> Cu2+(aq) + 2Ag(s)

This represents the actual species involved in the reaction and shows the transfer of electrons between them.

One piece of evidence that a chemical reaction has occurred is the formation of a solid (silver) from a solution. This indicates a change in the chemical properties and composition of the substances involved, which is a key characteristic of a chemical reaction. Other evidence could include a change in color, temperature, or the release of gas.
 

1. What is the purpose of the Copper & Silver Nitrate reaction?

The purpose of this reaction is to observe and study the chemical changes that occur when copper metal is added to a solution of silver nitrate.

2. What are the products of the Copper & Silver Nitrate reaction?

The products of this reaction are copper nitrate and silver metal.

3. What type of reaction is the Copper & Silver Nitrate reaction?

This reaction is a single replacement reaction, where a more reactive element (copper) replaces a less reactive element (silver) in a compound.

4. What is the balanced chemical equation for the Copper & Silver Nitrate reaction?

The balanced chemical equation for this reaction is: Cu + 2AgNO3 → Cu(NO3)2 + 2Ag

5. How do you know if the Copper & Silver Nitrate reaction is a successful reaction?

A successful reaction will result in a visible change, such as a color change or formation of a solid. In this reaction, a reddish brown solid of copper will form, indicating that the reaction was successful.
