Activity Series Lab Grade 12 Chemistry

Purpose: The purpose of this lab is to investigate the reliability of the activity series of metals by testing in solution, confirming if the activity series was correct with its predictions.

Hypothesis: It is predicted that the metals in solid form will displace metals in solution if located higher over the other within the activity series chart.

Observations & Analysis:
Metals & Solutions Prior to Reaction Post Reaction Analysis
Aluminum & Copper (II) Chloride -Blue translucent liquid
-Small silver ball -Grew ten times original size
-Rust Color
-Clear transparent liquid A buildup of residue formed and the clear solution became cloudy with flaky matter.

Iron & Magnesium Chloride -Clear transparent liquid
-Silver nail - No Reaction

-No reaction
Zinc & Lead (II) Nitrate -Clear transparent liquid
-Silver clump -Black and shiny

Black powdery crystals formed within the solution and around the Zinc.
Magnesium & Nickel Nitrate -Green liquid
-Silver shiny strip of magnesium
-Floats -Bubbles
-Solution Green
-Silver strip of Magnesium
-Floats The strip of Magnesium floated and oxidized within the solution. Bubbles formed and the solution colored but more blue than green.
Zinc & Calcium Nitrate -Clear transparent liquid
-Silver ball -Flattened
-Bubbled
-Still solid The Zinc flattened out and bubbled as it oxidized. It still remained a solid but it broke down in solution.
Aluminum & Tin (II) Chloride

-Foggy liquid
-Silver shiny Aluminum foil
-Malleable
-Black Flakes
-Dissolves

The Aluminum started to melt and break down into black flakes and sink to the bottom. The solution
