Question

State an obstacles due to which the true color of metal ions not always be seen quiz let

Answer 1

Answer:

hey

Explanation:

It may because

of deposition of dust....or corrsion

Answer 2

Answer :

• Metals are highly reactive in nature. They react with air and water vigorously and hence form new compounds and thus changes the colours.
• The degenerate d orbitals prevent the metal ions from naturally taking on colour.
• They all share the same energy, or the same spectral signal, in other words. Transition metal ions take on colour when they join forces with other molecules to create complexes and compounds.
• Ions have colours that are complimentary to the colours they absorb.
• Corrosion is demonstrated by the appearance of rust on iron, tarnish on silver, and a blue-green patina on copper.
• In aqueous solution, transition metals form coloured ions, complexes, and compounds. When performing a qualitative analysis to determine the composition of a sample, the characteristic colours are useful.
• The colours also reflect the fascinating chemistry that takes place in transition metals.
