A student attempts to identify six solutions that contained either iron(II) bromide, potassium bromide, potassium sulfate, dichloromethane (CH2CI2), ammonium nitrate, and iron(II) sulfate. The tests performed were conductivity, solution colour, flame colour, and the addition of barium nitrate solution. The following evidence was collected: Conductivity Flame Colour Solution Colour Addition of Ba(NO3)2(aq) Solution yes colourless No precipitate formed none none colourless No precipitate formed none yes lime green Precipitate formed none yes violet colourless Precipitate formed yes none lime green No precipitate formed yes violet No precipitate formed none

A student determined the chloride content of a commercial salt by using the Mohr method. A 0.7725 -g sample of the salt was dissolved in distilled water and diluted to a final volume of 250. mL. A 25.-mL aliquot of the analyte solution was then titrated against a standard 0.0347 M AgNO3(aq) solution to the chromate end-point. A blank-corrected volume of 25.96 mL was recorded. Calculate the percent chloride in the sample.
