Na2CO3 is used to standardize a solution of HCl. What is the concentration of HCl if 0.1970 g of pure Na₂CO3 dissolved in 50.00 mL of water took 29.41 mL of HCl to reach the end point in the titration? Next, 0.4242 g of an unknown sample containing Na2CO3 was dissolved in 50.00 mL of water. It took 18.92 mL of the standardized HCl solution to reach the end point in the titration of the unknown sample. What is the wt% of Na₂CO3 in the unknown? M HCI wt % Na₂CO3
