Potassium reaction with air.
Soft. Shiny which quickly tarnishes.
Burns with a lilac flame.
Sodium reaction with air.
Soft. Shiny which quickly tarnishes.
Burns with a yellow flame.
Calcium reaction with air.
Forms oxide layer.
Burns with a brick red flame.
Magnesium reaction with air.
Forms oxide layer.
Burns with a bright white flame leaving white ash.
Aluminium reaction with air.
Forms oxide layer.
Sheets don’t easily burn.
Powder burns with white sparks leaving white solid.
Zinc reaction with air.
Forms oxide layer.
Burns leaving yellow solid which cools to white.
Iron reaction with air.
Oxide layer rubs off.
Sheets don’t easily burn.
Filings burn with yellow/orange sparks leaving black solid.
Copper reaction with air.
Oxide layer rubs off.
Sheets form black oxide layer. Forms without heat.
Potassium reaction with water.
Floats, moves around surface. Burns with lilac flame. Hydrogen bubbles released. Colourless solution formed.
Sodium reaction with water.
Floats, moves around surface. Melts + forms sphere. Burns with yellow flame. Hydrogen bubbles released.
Colourless solution formed.
Calcium reaction with water.
Granules sink, hydrogen bubbles released. Exothermic.
Magnesium reaction with water.
Few hydrogen bubbles.
Aluminium, Zinc, Iron + Copper reaction with water.
No reaction. Iron rusts after a few days.
Magnesium reaction with steam.
Produces bright white light and leaves white powder.
Aluminium reaction with steam.
Foil doesn’t react. Small pieces react with oxide layer rubbed off. Powder forms white powder.
Zinc reaction with steam.
Glows,produces yellow powder which cools to white.
Iron reaction with steam.
Must be heated until glowing red. Forms black solid.
Calcium, Magnesium, Aluminium + Zinc reaction with acid.
Hydrogen bubbles produced. Metal disappears. Colourless solution formed. Exothermic.
Copper reaction with acid.
No reaction
What is a displacement reaction?
A more reactive element displaces a less reactive element from its compound.
Observations: Magnesium + copper sulfate
Turns from blue to colourless. Red-brown copper formed.
Observations: Magnesium + iron sulfate
Pale green to colourless. Solid formed.
Observations: Iron + copper sulfate
Blue to pale green. Solid formed.
Observations: Zinc + copper sulfate
Blue to colourless. Solid formed.
Observations: Copper + silver nitrate
Colourless to blue. Solid formed.
Observations: Magnesium + zinc nitrate
Surface of Mg turns darker/black
Observations: Tin + copper sulfate
Surface tarnishes with pink-brown copper layer. Solution colour fades.
Observations: Iron + copper sulfate
Surface of iron coated with pink-brown copper. Solution fades.
Observations: Zinc + lead nitrate
Surface darkened w/ sparkly crystals.
Observations: zinc + copper sulfate
Surface coated with pink-brown copper and blue surface fades.
