Sodium bicarbonate undergoes hydrolysis to form sodium hydroxide and carbonic acid. Carbonic acid is a weak acid and sodium hydroxide is a strong base, thus making the solution basic. The bicarbonate ion hydrolyzes according to the equation: HCO3- + H2O H2CO3 + OH-, creating a basic solution.

A lab group decides to test a manufacturer’s claim that an antacid product contains 200 mg of sodium bicarbonate. Each tablet was placed into an Erlenmeyer flask, 10.00 mL of water was added, and then the tablets were crushed. An indicator was added to each flask, and then each sample was titrated with 0.200 mol/L hydrochloric acid.

1. Fill a large, clean test tube slightly more than half full with sodium thiosulfate (Na2S2O3 • 5 H2O) crystals. Sodium thiosulfate is a hydrated crystal: it contains water molecules chemically bonded to the crystal-lattice structure. 2. Using a utility clamp, heat the test tube containing the sodium thiosulfate.

Even though sodium bicarbonate is only a weak base, the neutralization of acetic acid by the bicarbonate ion can be coerced to completion, because one of the neutralization products, carbonic acid (H 2 CO 3), is unstable and decomposes to carbon dioxide, …

Sodium bicarbonate + “magic water” chemical ( gas (carbon dioxide) + other compounds. ... Testing solubility in water: Take a grain of rice size sample (this is very, very small, much smaller than a pinch) of sucrose and place it in a well of your well plate. Repeat until you have a small amount of each sample, each in its own well.

a) Add a small scoop of baking soda, sodium bicarbonate, to a test tube and add water to height of about 1 centimeter. Stir. b) Add a few drops of silver nitrate solution to the baking soda solution. c) In another test tube place the same amount of baking soda and dissolve as above. Add hydrochloric acid. CAUTION: ACID CAN CAUSE SEVERE BURNS.
