First we need to deterine the extinction coefficient for the system at 710 and 740 nm. At the highest [HCl] the solution is essentially all [CoCl4]-2, the [Co(H2O)6]+2 can ignored. What is the extenction coefficient for 740 nm?

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm
