the answer is "in cold water"
[Co(CN)₆]³⁻ → Yellow
[Co(NH₃)₆]³⁺ → Orange
[CoF₆]³⁻ → Blue
Explanation:
- All the given compounds have octahedral geometry but the ligand in each are different with the same metal ion.
- Ligands strength order: CN⁻ > NH₃ > F⁻
- The ligand CN will act as a strong field ligand so that the splitting is maximum when compared to NH₃ and F⁻
- If the splitting is more, the energy required for transition is more, and the wavelength is inversely proportional to energy.
- So CN complex will absorb at lower wavelength (yellow color)
Due to presence of impurities further purification is needed.
A further purification is needed of the final product because of the presence of impurities in the final product. Further purification can also be done in order to gain pure product. There are various ways and methods which can be used for the purification such as Sublimation, Crystallization, Distillation, Differential Extraction and Chromatography.
These methods can be used for further purification and helps in the extraction of pure solution of final product so we can conclude that due to presence of impurities further purification is needed.

Answer:
The correct option is: A. H₂SO₄
Explanation:
Acid is a charged or a neutral molecule that is a proton donor and electron pair acceptors.
Acids can be classified into monoprotic acids and polyprotic acids.
Monoprotic acids are the acids that can release only one proton on dissociation.
Whereas, polyprotic acids are the acids that can release more than one proton on dissociation.
Diprotic acid is a type of polyprotic acid that can release two protons on dissociation. Example: H₂SO₄
Geosphere >> Which is Earth's entire solid body..
Hydrosphere >> Which is all the "liquid" water on Earth..
Atmosphere >> Which is the few layers of "gasses" that are surrounding Earth..
Cryosphere >> Which is all the "frozen" water on Earth..
Biosphere >> Us! All the living organisms on Earth..
