**Prelaboratory Assignment: Analysis of an Unknown Chloride**

1. **A sample containing 0.175 g of Cl⁻ is dissolved in 50 mL of deionized H₂O. The solution is titrated to the equivalence point with a AgNO₃ solution. The final volume of the titrated sample is 75 mL.**

   a) What is the concentration of the AgNO₃ solution?
   
   *(Answer space: __________________________)*
   
   b) How many grams of AgCl are precipitated?
   
   *(Answer space: __________________________)*

2. **A student wishes to determine the mass percentage of barium in a 2.016 g sample. The student titrated the sample with 20 mL of 0.20 M H₂SO₄, producing a BaSO₄ precipitate.**

   a) How many moles of BaSO₄ were formed in the titration?
   
   *(Answer space: __________________________)*
   
   b) What was the mass of barium present in the original sample?
   
   *(Answer space: __________________________)*
   
   c) What was the mass percent of barium in the original sample?
   
   *(Answer space: __________________________)*

3. **An unknown sample weighing 0.2358 g is titrated to the endpoint with 47.28 mL of a 0.10 M AgNO₃ solution. What is the weight percent of Cl⁻ in the sample?**
