A student determines the concentration chloride in an unknown sample by pipetting 10 mL of the sample and 10 mL of 1.000 × 10−5 M quinine solution to a 100 mL flask and diluting to volume with 1 M H2SO4.A series of six chloride standards were prepared using a 0.0100 M standard chloride solution,adding an increasing volume of chloride to 100 mL volumetric flasks,in addition to 10 mL of 1.000 × 10−5 M quinine.Each solution was diluted to volume with 1 M H2SO4.Calculate the chloride concentration for the unknown using the collected fluorescence data and the Stern-Volmer graph below for the data.
