This includes Plutonium, Chromium, Nickel, IronAlkaline test, Acidic test, Chromyl chloride test, and Baeyer’s reagent test
The number of unpaired electrons in gaseous species of Mn3+, Cl3+ and V3+ respectively are and the most stable species is
Colour of transition metal ions are due to absorption of some wavelength. This results in
The melting points of Cu, Ag and Au follow the order
In which of the following pairs of ions, the lower oxidation state in aqueous solution is more stable than the other?
Fe3+ ion is more stable than Fe2+ ion because
More the charge on the atom, more is its stability
Configuration of Fe2+ is 3d5 while Fe3+ is 3d5
Fe2+ has a larger size than Fe3+
Fe3+ ions are coloured hence more stable
