4. A 0.1036-g sample containing only BaCl2 and NaCl is dissolved in 50 mL of distilled water. Titrating with 0.07916 M AgNO3 requires 19.46 mL to reach the Fajans endpoint. Report the %w/w BaCl2 in the sample.
A 1.000 liter sample of sea water was evaporated to a small volume and treated with an excess of sodium tetraphenylboron. The precipitated tetraphenylboron was filtered and then redissolved in acetone. The analysis was completed by a Mohr titration that required 34.32 ml of 0.03875 M AGNO3. Calculate the parts per million of potassium in the sea water sample. K* + NaB(C,Hs)4 → KB(C,Hs)4(s) + Na* ; Ag* + KB(C,H5)4 > AgB(CgHs)4(6) + K*

You want to measure the concentration of carbonate (CO32-) in a mildly basic solution by using an EDTA back titration. CaCO3 has a Ksp of 5x10-9. You add 50.00 mL of 0.3484 M CaCl2 to 500.0ml of sample and filter the solution to remove the precipitate. You then take 250.0 mL of the filtered solution and titrate with 0.1786 M EDTA. You require 23.72 mL to reach the endpoint. What is the concentration of carbonate in the original sample?
