• \(`Zn(NO_3)_2`\): A colourless seemingly clear liquid
• \(`Cu(NO_3)_2`\): A sky blue liquid
  
• \(`AgNO_3`\): A colourless seemingly clear liquid
• \(`Mg`\): light gray in colour
• \(`Cu`\): orangish brown in colour
• \(`Zn`\): dark gray in colour
• \(`Ag`\): silver, very light gray in colour

Element/Compound	\(`Mg(NO_3)_2`\)	\(`Zn(NO_3)_2`\)	\(`Cu(NO_3)_2`\)	\(`AgNO_3`\)
\(`Mg`\)	N/A	The previously gray rod has now gotten a black coating around it The solution has not changed much	The previously gray rod has now gotten a light brownish coating around the rod, the solution has gotten a tiny bit lighter blue.	The previously gray rod as now gotten a very light gray coating around the rod. Not much change in the solution.
\(`Zn`\)	Nothing changed	N/A	The solution has gotten a bit lighter, the gray rod now has a brownish coating around it	The previous dark gray rod now has a silver/light gray coating around it, nothing changed in the solution
\(`Cu`\)	Nothing changed	Nothing changed	N/A	The previously brown rod now has a silver/gray coating around it, and the solution turned torquoise
\(`Ag`\)	Nothing changed	Nothing changed	Nothing changed	N/A
