Reactivity and displacement Flashcards
How can metals be arranged in a reactivity series
Q. By their reactions with water
W. By their reactions with hydrochloric or sulfuric acid
Metals can be arranged in a reactivity series based on their reactions with ——— and —————-.
- Metals
Metal oxides
State the reactivity series
Potassium Sodium Lithium Calcium Magnesium Aluminium Zinc Iron Copper Silver Gold
Define oxidation in terms of oxygen
The gain of oxygen
Define reduction in terms of oxygen
The loss of oxygen
Define oxidation in terms of electrons
The loss of electrons
Define reduction in terms of electrons
The gain of electrons
What is a redox reaction
A reaction where both reduction and oxidation occur
What is a reducing agent
A reducing agent causes another substance to be Reduced. In the process it is oxidised.
Define an oxidising agent
An oxidising agent causes another substance to be oxidised. In the process it is reduced.
What is a displacement reaction?
A displacement reaction is where a less reactive metal gets pushed out of its compound by a more reactive metal.
Describe a test for the reactivity of a metal.
One should react each metal individually and time how long it takes for the effervescence to stop the shorter the time the more reactive the metal.
