SALTS
What is a salt in chemistry?
A salt is a chemical compound formed when an acid reacts with a base,
resulting in the replacement of hydrogen ions in the acid by metal ions
or other cations.
How are salts classified?
Salts are classified into normal salts, acid salts, basic salts, and double
salts based on their chemical composition and reactions.
What is a neutralization reaction?
A neutralization reaction occurs when an acid reacts with a base to
produce salt and water.
What is the pH of a neutral salt?
The pH of a neutral salt is typically 7, indicating no excess of hydrogen or
hydroxide ions.
Why do salts conduct electricity in water?
Salts conduct electricity in water because they dissociate into ions, which
are charged particles that carry electric current.
What is a common example of a salt?
Sodium chloride (NaCl), commonly known as table salt, is a well-known
example of a salt.
How are insoluble salts prepared?
Insoluble salts are prepared through a double displacement reaction or
precipitation reaction between two soluble compounds.
, What determines the color of a salt?
The color of a salt is determined by the metal ion or cation it contains,
such as copper sulfate being blue due to copper ions.
What happens when salts are heated?
When salts are heated, they may decompose, releasing gases or forming
new substances depending on their chemical structure.
Why do some salts absorb water from the air?
Some salts, known as hygroscopic or deliquescent salts, absorb water
from the air because they have a strong affinity for moisture.
What is the difference between a hydrated salt and an anhydrous salt?
A hydrated salt contains water molecules as part of its crystal structure,
whereas an anhydrous salt does not.
What is the chemical formula of Epsom salt?
The chemical formula of Epsom salt is MgSO₄·7H₂O, which represents
magnesium sulfate heptahydrate.
How can you test for the presence of chloride ions in a salt?
The presence of chloride ions can be tested by adding silver nitrate
solution; a white precipitate of silver chloride confirms chloride ions.
What are double salts?
Double salts are compounds that contain two different cations or anions
and form when two salts crystallize together.
Why is sodium carbonate called a basic salt?
Sodium carbonate is called a basic salt because it hydrolyzes in water to
produce hydroxide ions, making the solution alkaline.
