Chapter 2 Flashcards
What is the ACID And BASE according to the Arrhenius theory
Acid is substances that ionises in water to give hydrogen ions (H+)
For example HCl
Base Is substances that are you nice to give hydroxide ions (OH)
For example NAOH
What is acid and base according to Bronsted-Lowry theory
Acid is the substance which donate Proton

Base is the substance which accept proton 
Bronsted - Lowry theory assumes …
Transfer of protons from an ACID to a BASE
Conjugate pairs 
Free protons do not exist in the solution that’s why we can write a half reaction
True or false 
True
The acid and Base Off a half reaction are called
Conjugate Pairs
Define the amphoteric and give an example
Is a species that can act as an acid or base
For example the water
Define the Conjugate base
Species that remains after an ACID donates it is H+
Define conjugate Acid
Species remains after base accept H+
What is the acid and base according to lewes theory
Acid is the substance which accept lone pairs of electrons
For example ALCL3
Base is substance which donate lone pairs of electrons
for example NH3
Lewis theory assume what
Donation of electrons from a base to an acid
Classified the solutions
Electrolyte which dissociate and conduct electricity
None electrolytes Which don’t ionise and don’t conduct electricity 
When an acid or base is dissolved in water the Amount of disassociation depend on
The strength of the ACID, BASE
Give an example for weak acid and strong acid
Strong acid: hydrochloride acid HCl 
weak acid: Acetic acid CH3COOH 
Give an example for strong base and weak base
Strong base NAOH
Weak base NH4OH
Define the Kw and it’s product of what
It is the molar equilibrium constant
It’s Product of the hydrogen concentration and hydroxide ion concentration [H+][OH-]
