Purpose: The purpose of this lab is, to determine the double/single displacement reactions and how they relate to the activity series/solubility chart.
Hypothesis:
Observations:
Before | After |
Copper (II) Sulphate | Color : Blue Transparent State: Liquid | Copper Floats | Magnesium Change colors and also started to rust. Bubbles we forming and eventually was formed. |
Zinc Nitrate | Color: Clear Transparent State: Liquid | Floats No reactions was happening | Floats No reaction was being made. There was a color change being made. |
Magnesium Nitrate | Color: Clear Transparent State: Liquid | Floats No reactions was happening | Floats No reaction was being made. Bubbles were being formed underneath the liquid. |
Iron (II) Nitrate | Color: yellow ish and some parts clear. Transparent State: liquid | The element sunk. This also had no reaction. | Floats No reaction was being made. Rust was being formed and it started to create crust. |
Zinc Bubbles were being formed under the strip. Precipitate turns cloudy, and turned black. |
Sinks No reaction was being made. |
No reaction was being made. The element sunk. |
No reaction was being made. The element sunk. |
Iron Sinks Changes color and turns white. | ||
No reaction was being made. The element sunk. | ||

No reaction was being made. The element sunk |
Before | After |
Nickel (II) Nitrate | Dear Green tint | + sodium carbonate Foam Mint Green Bubble cloudy Separation white Precipitation |
Barium Nitrate | Dear Colorless | Separation white Precipitation |
Lead Nitrate | Colorless | + potassium iodide Opaque Precipitate Cloudy |
Sodium Carbonate | Clear |
Analysis: Answer the following question:
What evidence suggests that chemical reactions occurred?
Firstly, chemical reaction means, a process in which one or more substances are changed into another substance.
In this experiment, I got to identify and also see the chemical reactions for...
