Ti(H2O)6]3+ is coloured while [Sc(H2O)6]3+ is colourless. Why ?

In this study, a light-coloured eye is a dominant trait because children born from parents having light-coloured eyes also had light-coloured eyes.

[Hint : NO2 gets condensed to N2O4.]

[Hint  :  H2O molecules are stabilized by intermolecular hydrogen bonding, while H2S by weak van der Waal’s forces.]

[Hint : NaCl + H2SO4 (conc.)->  NaHSO4 + HCl]

Because water molecules act as ligands and results in crystal Fleld splitting of d-orbitals of Cu2+ ion.

Due to charge transfer complex formation.

CuSO4 does not has any ligand, so splitting of d-orbital take place while CuSO4.5H2O has water ligand.

This is done in order to cut off light because hydrogen peroxide decomposes into water and oxygen in the presence of light.

The band of the coloured components of white light. Refractive index speed of light is different for different colours.  By placing a second identical prism in an inverted position with...
