The spin only magnetic moment of the complex present in Fehling's reagent is____ B . M . (Round off your answer to the nearest integer)

Step-by-step solution

Fehling's solution consists of two parts A and B. Fehling’s solution A is deep blue colour due to the bis(tartrate) complex of Cu 2 + . Fehling's solution B is the Rochelle salt (potassium sodium tartrate tetrahydrate) serves as a chelating agent in the solution. Fehling solution is a complex of Cu + + Cu + + = 3   d 9 Number of unpaired e - = 1 Magnetic   Moment = 1 1 + 2 = 3 = 1 . 73 BM
