What will happen when zinc is placed in copper (II) sulfate?
What will happen when copper is placed in copper (II) sulfate?
Prediction
It is predicted that when you place zinc and copper (II) sulfate a reaction will occur, resulting in a precipitation.
The prediction about the copper (II) sulfate and copper is that nothing will happen.
Hypothesis
It is hypothesised that when zinc is placed in aqueous copper (II) sulfate, a single displacement reaction will occur as the zinc is in its elementary form. Because it has a higher reactivity, it will probably displace the copper from copper (II) sulfate and a precipitation will be present.
It is hypothesised that no reaction will occur between the copper (II) sulfate and the …show more content…
A pellet of zinc is then placed in the first well with the help of safety gloves, and one copper wire is put in the second one. An important step is the adding of powder sodium chloride to both of the wells of the spot plate with the help of a red spoon. The well with the zinc is agitated well twice in a couple of minutes interval, again using the red spoon. After observations are made, the zinc is removed from the well and is put in a petri dish with the same type of spoon. The copper wire is also isolated from the solution and placed in a separate 100ml beaker. The copper roll is not used for the experiment but for further discussion regarding the experiment. The last step of the experiment is to mix the solutions from the two wells in a 500ml …show more content…
This change in the arrangement of atoms most of the times results in the physical properties of the elements that are interacting. As of the experiment, when the copper wire and copper (II) sulfate were put together, no physical change was observed. Moreover, copper is not an active metal and does not react with diluted acids. This leads to the conclusion that no reaction occurred between them.
