A mixture containing only KCl (74.55 g/mol) & NaBr (102.89 g/mol) was analyzed by the Mohr method. A 0.50 g sample which was dissolved in 50 mL of water and treated with 0.500 mL of 0.0010 M sodium chromate, required 10 mL of 0.50 M AgNO3 for complete titration. AgCl FW=143.32 g/mol , AgBr FW=187.77 g/mol. What type of precipitation method was used? What is the suitable indicator in the titration? What is the %w/w KCl in the sample? What is the %w/w NaBr in the sample?Single choice. What is the expected end point?
