e) via:. Lisbeth Myla CHEM 3321 A Back titration - Homework A solution containing Cl- was analyzed as follows in a back titration. A solution containing (excess) Ag + is added, and the AgCl precipitate is filtered and removed. The excess Ag is then titrated with SCN- Ag+ (aq) + Cl(aq) - Ag+ (aq) + SCN (aq) -------> AgCl (s) --------> AgSCN (aq) In one analysis, 25.00 mL of 0.01840 M AgNO3 (aq) was added to 50.00 mL of a solution containing dissolved chloride. The resulting AgCl (s) was filtered and removed. The excess Ag+ (aq) remaining required 14.25 mL of 0.02008 M SCN (aq) to reach the endpoint. What is the original concentration of Cl (aq) in the original 50.00 mL soln?
To prepare 100 mL of TE buffer (10mM Tris and 1mM EDTA) What volumes of the above Tris (1M) and EDTA (0.2M) solutions should be used?
