What else can I help you with?
Tightly-bound group of atoms that behaves as a unit and carries a net charge?
An ionized molecule. Common examples are Sulphate ions, Nitrate ions and Phosphate ions.
How many ions are present in ammonium sulphate?
Ammonium sulphate consists of two ions: ammonium (NH4+) and sulphate (SO4^2-).
Why do you add hydrochloric acid to test for sulphate?
Hydrochloric acid is added to a solution being tested for sulphate ions to precipitate the sulphate as barium sulphate. This is a confirmatory test for the presence of sulphate ions in the solution because barium sulphate is insoluble and forms a white precipitate.
What is the type of particle of sodium sulphate?
Sodium sulphate is an ionic compound composed of sodium ions (Na+) and sulphate ions (SO4^2-). It is not a single particle but a crystalline solid made up of a repeating pattern of these ions.
Does copper sulphate dissolved in water?
Yes, copper sulphate can dissolve in water. When added to water, copper sulphate dissociates into copper ions (Cu2+) and sulphate ions (SO4 2-), forming a blue-colored solution.
Charge of sulfate?
The charge of sulfate, represented by the chemical formula SO4^2-, is 2-.
Tightly-bound group of atoms that behaves as a unit and carries a net charge?
An ionized molecule. Common examples are Sulphate ions, Nitrate ions and Phosphate ions.
How many ions are present in ammonium sulphate?
Ammonium sulphate consists of two ions: ammonium (NH4+) and sulphate (SO4^2-).
IF A solution of copper sulfate is a conductor what particle is serve as charge carrier?
In a solution of copper sulfate, the charge carriers that help it conduct electricity are the copper ions (Cu2+) and the sulfate ions (SO4 2-). These ions are free to move in the solution and carry electrical charge.
Why aqueous copper sulphate solution conduct electricity but solid copper sulphate does not?
Aqueous copper sulfate solution contains free ions (Cu2+ and SO4 2-) that can carry electrical charge and allow the solution to conduct electricity. In contrast, solid copper sulfate does not contain free ions and is unable to conduct electricity because the ions are locked in a fixed position within the solid lattice.
Why do you add hydrochloric acid to test for sulphate?
Hydrochloric acid is added to a solution being tested for sulphate ions to precipitate the sulphate as barium sulphate. This is a confirmatory test for the presence of sulphate ions in the solution because barium sulphate is insoluble and forms a white precipitate.
What is the type of particle of sodium sulphate?
Sodium sulphate is an ionic compound composed of sodium ions (Na+) and sulphate ions (SO4^2-). It is not a single particle but a crystalline solid made up of a repeating pattern of these ions.
Does aluminium sulphate conducts electricity?
Yes if it's molten or dissolved in water as the ions (charged particles) can move. No when in solid state as the ions can't move out of position so there is/are no charge/ no free electrons.
Does copper sulphate dissolved in water?
Yes, copper sulphate can dissolve in water. When added to water, copper sulphate dissociates into copper ions (Cu2+) and sulphate ions (SO4 2-), forming a blue-colored solution.
How do you test for sulphate ions?
add barium chloride or barium nitrate to a solution containing sulphate ions SO4 2-. To the same solution add hydrochloric acid in excess. OBSERVATIONS, a white precipitate which is insoluble in excess acid confirms presence of SO42- IF IT DISSOLVES then it confirms SO32- ----------------------------------------- 1) Add barium nitrate solution under acidic conditions (use an equal volume of hydrochloric acid) to the unknown solution 2) A white precipitate of barium sulphate forms if sulphate ions are present
What happens to copper sulphate when added to water?
When copper sulphate is added to water, it dissociates into copper ions (Cu2+) and sulphate ions (SO4 2-). This forms a blue-colored solution due to the presence of copper ions in the water.
What is the symbol potassium sulphate?
The symbol for potassium sulphate is K2SO4 . It contains K+ and SO42- ions.
