- Abstract
- Silver in thiosulfate fixing baths can be determined when instruments or special equipment is not available. Silver is precipitated as silver sulfide when a thiosulfate fixing bath is treated with thioacetamide. The silver is titrated, in effect, by adding graduated amounts of thioacetamide to aliquots of the fixing solution and then determining if all the silver has been precipitated. Each aliquot is filtered and the filtrate is allowed to run into more thioacetamide solution. Formation of more silver sulfide precipitate indicates that the end point has not been reached. If no precipitate forms, the end point has been exceeded. The method is most useful if only an approximate result is required or especially if a go-no-go type of decision is needed.
