c. HCl in Sodium Carbonate. 1. Fill another 125ml Flask to the 50 ml mark with 0.05M NaHCO3 (sodium carbonate) solution. 2. Use the pH meter to record the initial pH of the solution by immersing the electrode and stirring. it in the solution. 3. Add HCl drop by drop, counting the drops while stirring with the pH electrode, until the pH

Less common soil carbonates include sodium carbonate (Na2CO3) and siderite (FeCO3). Carbonates buffer soil pH and are an indication of the relative abundance of bases. The presence of Ca+2 promotes clay flocculation. Besides these pedogenic implications, carbonate minerals play an important role in soil management (Doner and Lynn, 1989).

Titration of Sodium Carbonate with Hydrochloric Acid. Objectives: In this experiment, a solution of Na2CO3 will be titrated with a solution of HCl. The pH of the solution will be monitored as the HCl is added with a pH probe attached to a CBL. The shape of the pH titration curve will be observed and the Kb values for the base will be determined.

Sodium carbonate is an important industrial chemical. It is used in the manufacture of soap, glass, paper and as a source of alkalinity, that is, as a base. About half the sodium carbonate used in the United States is manufactured by the Solvay process.

PART IIIB: Data Recording – Sodium Carbonate. Repeat the procedure with 1.0 g of sodium carbonate solid in place of the ammonium chloride. Put 20 mL of distilled water in the inside cup. Measure 1.0 g of sodium carbonate on a piece of weighing paper. DON’T add the solid to the liquid yet. Put the lid on the cup.
