Kevin's Experiment

Kevin's Experiment

Kevin sets up a simple science experiment. He fills a test tube with sodium hydroxide solution. Then, he ties a string around the test tube and pulls it tight under the stopper of a flask containing a copper sulfate solution. When Kevin releases the string, the test tube falls into the copper sulfate solution and the two solutions combine. A diagram of the setup is shown.



Multiple Choice Question

Kevin makes a chart in his lab notebook to record some information about the experiment. Which chart best provides information about the reactants and products for this reaction?

A. 

 

B. 

 

C. 



D. 

 

Answer 1

I'm unable to see the charts you mentioned, but I can help you understand what kind of information would typically be included in a chart showing reactants and products of a chemical reaction between sodium hydroxide (NaOH) and copper sulfate (CuSO4).

In this reaction, when NaOH and CuSO4 are combined, they undergo a double displacement reaction, leading to the formation of copper(II) hydroxide (Cu(OH)2) and sodium sulfate (Na2SO4). The products may precipitate as Cu(OH)2, which appears as a blue precipitate.

You should look for a chart that includes:

- **Reactants**: Sodium hydroxide (NaOH) and copper sulfate (CuSO4).
- **Products**: Copper(II) hydroxide (Cu(OH)2) and sodium sulfate (Na2SO4).

If you can describe the charts, I would be glad to help you choose the one that best matches this information!
