The solution of CuSO4 is blue.
The solution of FeSO4 is green.
In an aqueous solution the solvent is water.
Sounds like copper (II) sulfate (ie cupric sulfate or CuSO4)
red or green if it's not completely finished
As gaseous ammonia with solid coppersulfate: 2NH3(g) + CuSO4(s) --> Cu(NH3)2SO4(s) With water: [Cu(NH3)2]2+ complex-ions with SO42- ions in aquous solution (deep blue color)
The aqueous solution of Cu2+ ions appears blue due to the absorption of certain wavelengths of light. The blue color is a result of the d-d electron transitions within the copper ions, where the electrons absorb energy and transition to higher energy levels, leading to the absorption of specific colors in the visible spectrum, giving the solution its characteristic blue color.
The aqueous solution of ferrous sulphate is typically pale green in color.
A ferrous sulfate solution typically appears colorless or pale green. When heated, the color may change due to oxidation reactions, resulting in a yellowish color or possibly forming a brown precipitate.
In an aqueous solution the solvent is water.
Sounds like copper (II) sulfate (ie cupric sulfate or CuSO4)
An aqueous solution of silver ions (Ag+) typically appears colorless. However, if there are silver nanoparticles present in the solution, it may show a yellow hue.
The sodium ion, Na+, has no color. You can observe this easily by dissolving table salt (NaCl) in water. The water does not change color.
The aqueous color disolved to .001 M of iron nitrate is purple or violet. (Not brownish orange). The individual crystals in a dry state are also a pale violet color.
It creates a clear aqueous solution with a blue tint.
Usually chromium with an oxidation state of +6 MnO4- will also impart a purple color in a solution
The blue color of the copper sulfate solution turns green when an iron nail is added because a chemical reaction occurs where iron displaces copper in the solution, forming iron sulfate and copper metal. The green color is due to the presence of copper metal particles in the solution.
An aqueous solution of copper sulfate absorbs light in the blue-green region of the spectrum. This is because copper ions in the solution absorb light of longer wavelength, leaving behind the blue-green color.
The universal indicator would likely show a green color in an aqueous solution of sugar. This is because sugar is a neutral compound and does not significantly affect the pH of the solution, resulting in a green color indicating a neutral pH.
