Answer»

It is REDOX reaction inwhich green solution of `[Cr(H_2O)_6]^(+3)`is produced.
One of the product in reaction has TRIGONAL planar structure.
Dimeric bridged tetrahedral METAL ion is produced.
Dark blue COLOUR is obtained in reaction.

Solution :`underset("(Yellow)")(2CrO_4^(2-))underset(OH^(-))overset(2H^(+))hArrunderset("(Orange)")(Cr_2O_7^(2-))+H_2O`
