The same reaction occurs when calcium is added to a carbonate buffer solution. In this reaction, CaCO3 is the most insoluble product with a Ksp = 4.96x10-9 (6). This product forms from a 1:1 ratio of calcium and carbonate and it is therefore predicted that the amount of carbonate buffer consumed will equal the amount of Ca2+ that reacts.

1. Sodium, potassium, and chloride function primarily in fluid balance. 2. Calcium, phosphorus, and magnesium function primarily in bone growth and health. III. Sodium. Sodium is one of the primary electrolytes in the body and is responsible for maintaining fluid balance. Dietary recommendations include a moderate intake of salt and sodium.

“When solid sodium bicarbonate is heated in a test tube, an invisible gas, carbon dioxide, is released into the surrounding air. Water condenses at the mouth of the test tube and a white solid residue, sodium carbonate, remains behind in the bottom of the test tube.”

Add a small scoop of sodium bicarbonate (baking soda) to the test tube. Stopper the tube, and shake it carefully to dissolve the sodium bicarbonate. Add about 2 mL of acetic acid solution (vinegar). Write down your observations. Discard your solution into the SOLUTIONS waste container Change 2: Get about a 2.5 cm piece of calcium carbonate (chalk).

Although these substances are effective, each one has certain disadvantages. For example, sodium bicarbonate loses its effectiveness quickly, and many people must limit their intake of sodium. Magnesium compounds can cause constipation, aluminum hydroxide can act as a laxative, and calcium carbonate has an unpleasant taste.
