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.
