Question

Calculate the volume in m) of silver nitrate solution that will be needed for the precipitation: normally the amount of silver nitrate required to precipitate all of the chloride in the sample is found by a trial and error process. However, to speed up the experiment, assume a sample mass of 0.1479 g, and that sample contains approximately 55.0% chloride ion by mass (some samples may contain more, some less), and calculate what volume of 0.100 M AgNO3 needs to be added to precipitate all of the chloride ion. (Note: When you actually do the experiment, add 5 ml. in excess of this volume. For example, if your answer of this question is 25 mL, you will need to use 30 ml of silver nitrate solution when you actually do the experiment, Pay attention to the sig.figs.in your calculation keep three sig figs in the answer.)
