1.	The complex ion [Ag(S2O3)2]^3- is associated with which field?(a) Electroplating(b) Medicine(c) Water treatment(d) PhotographyI had been asked this question during an internship interview.My enquiry is from Coordination Compounds Importance and Applications topic in section Coordination Compounds of Chemistry – Class 12
Answer» Right OPTION is (d) Photography For explanation I WOULD say: In black and white photography, the FILM is fixed by WASHING with hypo solution which dissolves the undecomposed silver bromide to FORM [Ag(S2O3)2]^3-.
