Qualitative analysis revealed that an unknown contained the anions. NO3-, Cl- and ClO3-. A student weighed a sample into a beaker and recorded the following data:
Weight of the beaker and sample 68.962 gramsWeight of beaker 67.625 grams
The sample was dissolved and diluted to 200.0 milliliters. A 50.00 milliliters portion of the solution was treated with excess silver nitrate solution, and the precipitate was collected in a filter crucible. Weighing gave the following data:
Weight of crucible and AgCl 10.211 gramsWeight of crucible 10.102 grams
Another 50.00- milliliter portion was treated with a reducing agent before the addition of excess silver nitrate solution. The precipitate which formed, was collected and weighed in another filter crucible.
Weight of crucible and AgCl 10.247 gramsWeight of crucible 10.110 grams
a) Determine the percentage of Cl- in the unkown.
b) Determine the percentage of ClO3- in the unknown.
