Reactivity series Flashcards
How to find the reactivity of metals?
Reacting the metal with water and dilute acids.
Order of a reactivity series (with carbon and hydrogen)
- Potassium
- Sodium
- Lithium
- Calcium
- Magnesium
- CARBON
- Zinc
- Iron
- HYDROGEN
- Copper
The reactivity of metal depends on…
the ability to lose electrons to form positive ions.
Reacting metal with water produces:
- metal hydroxide
- hydrogen
Water can be used to find the reactivity of…
first 4 metals.
How to speed up the reaction?
Heating up the metal and reacting it with steam.
Dilute acid is used for…
metals, which reactions are very slow. This speeds up the reaction.
A reaction of first 4 metals with water
- fizzing
- giving off hydrogen
- leaving an alkaline solution
A reaction of first 4 metals with dilute acid
-explosion
A reaction of second 4 metals with steam
-quiet slow react with steam
A reaction of second 4 metals with dilute acid
- fizzing
- hydrogen produced
- salt is produced
Copper has no…
reaction with water or dilute acid.
To test the presence of hydrogen
The gas pops with a lighted splint.
