When 50.0 mL of a 0.3000 M AgNO3 solution is added to (4.65x10^1) mL of a solution of MgCl₂, an AgCl precipitate forms immediately. The precipitate is then filtered from the solution, dried, and weighed. If the recovered AgCl is found to have a mass of (1.2x10^-1) g. what was the concentration in molarity of chloride ions in the original MgCl₂ solution? 2AgNO3(aq) + MgCl₂(aq) → 2AgCl(s) + Mg(NO3)2(aq) Use the correct number of significant figures and type in the unit abbreviation for the answer. Answer: 8.0x10^-1 M.
How many grams of pure Na2CO3 must be weighed and dissolved in a solution, if you are to prepare a 0.1478 N HCl that utilized 61.75 mL of titrant? MW Na2CO3 is 106 g/mol.
0.3456 g of a solid acid is dissolved in 50 mL of water in a flask and a few drops of phenolphthalein are added to the solution. A buret containing 0.2545 M NaOH is prepared with an initial volume of 10.50 mL. The acid is accidentally titrated with the base beyond the end point, so 1.52 mL of 0.187 M HCl are added to the flask. The titration with the base is continued to a final volume reading of 40.55 mL. Calculate the molar mass of the solid acid.

4. A solution of 75 mL NazCO3 is neutralized with 67.2 mL of 0.1065 M HCI. In the another analysis, 50 mL NazCO3 is added to a solution of 25 mL Ba(NO3)2, and after the barium carbonate was precipitated, the excess of NazCO3 is neutralized with 14.8 mL of the same acid. According to this, what is concentration of barium nitrate (261.337 g/mol) in molarity and g/L?
The antacid found in Tums™ has the active ingredient calcium carbonate, which undergoes a reaction when mixed with hydrochloric acid to produce water, calcium chloride and carbon dioxide.
