When silver (Ag) is added to a copper sulfate (CuSO₄) solution, a single displacement reaction inträffar. Här är vad som händer:

* Silver is more reactive than copper. This means silver has a stronger tendency to lose electrons and form positive ions (Ag⁺).

* Copper ions (Cu²⁺) in the solution are attracted to the silver. The silver atoms donate electrons to the copper ions, causing them to reduce to copper atoms (Cu).

* Silver ions (Ag⁺) are formed. The silver atoms that donate electrons become silver ions.

* The solution changes color. Den blå färgen på kopparsulfatlösningen bleknar när kopparjoner avlägsnas, och lösningen kan bli något molnig när kopparmetall utfaller ut.

Here's the chemical equation:

2Ag(s) + CuSO₄(aq) → Cu(s) + Ag₂SO₄(aq)

i enklare termer:

* Silver (Ag) displaces copper (Cu) from the copper sulfate solution.

* Silver forms silver sulfate (Ag₂SO₄) which dissolves in the solution.

* Copper metal (Cu) precipitates out of the solution as a reddish-brown solid.

Key observations:

* Formation of a reddish-brown solid (copper metal)

* Fading of the blue color of the copper sulfate solution

* Possible slight cloudiness in the solution
