Acids Flashcards
When an acid is added to water what ion is released into the soltution
H+/ Hydrogen Ion
Define Acid
Proton Donor
Describe the dissociation of a strong acid
Full dissociation
Define Base
Proton acceptor
Whic base is used to treat indigestion
MgOH
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
Metal Carbonate + Acid =
Salt + CO2 + H2O
What is a salt
A compound that is formed when H+ of an ion is replaced by a metal ion or positive ion
Metal Oxide + Acid =
Salt + H20
What is formed when acid reacts with alkali
Salt + H20
Metal + Acid =
Salt + H2
Why are the products the 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 crystaline 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
How do you carry out a titration
- Using a pipette, measure the volume of a solution
- Add the solution into a conical flask and add an indicator into it
- Add the other solution into a burette and record the volume
- Slowly add the other solution into the burrette and record the volume
- Swirl the mixture continously until the end point is reached
- Repeat untill concordant results are obtained
What is the colour of methyll orange in an acid, base and at end point
ACID-RED
BASE-YELLOW
ENDPOINT-ORANGE
