Module 2 - Acids Flashcards
When an acid is added to
water what ion is released into
the solution?
Hydrogen ion , H+
Define acid
Proton donor
Describe the dissociation of a
strong acid
Full dissociation
Define base
Proton acceptor
Which base is used to treat
acid indigestion?
Magnesium hydroxide
What are alkalis?
Bases that can dissolve in water to form
aqueous hydroxide ions
What are amphoteric
substances?
Substances that can act as acids and
bases
What is formed when acid
reacts with carbonate?
Salt, carbon dioxide and water
What is a salt?
A compound that is formed when H+
of
an ion is replaced by a metal ion or
positive ion
What is formed when acids
react with metal oxide?
Salt and water
What is formed when acid
reacts with alkali?
Salt and water
What is formed when acids
react with metal?
Salt and hydrogen
Why are the products same
when acid reacts with alkali or
metal oxides?
Both alkali and metal oxides are types of
bases
How are ammonium salts
formed?
When acid reacts with aqueous
ammonia
What are hydrated crystals?
A crystalline structure containing water
What does anhydrous crystals
mean?
Crystalline form that contains no water
What does a dot formula
indicate?
The amount of water present in a
crystalline structure
Write down the methods to
carry out a titration
- Using a pipette, measure the volume of a solution
- Add the base into a conical flask and add an indicator into it
- Add the acid solution into a burette and record the volume
- Slowly add the solution in the burette into the conical flask
- Swirl the mixture continuously until the end point is reached
- Repeat until concordant results are obtained
What is the colour of methyl
orange in an acid, base and at
end point?
● Acid - red
● Base - yellow
● End point - orange
