Description of experiment
Below follows a plain text transcript of the selected experiment.
Needed compounds:
-----------------
sodium bicarbonate : NaHCO3
silver nitrate : AgNO3
Class:
------
elem=Ag,C
precipitation
Summary:
--------
Silver (I) forms a yellow precipitate with bicarbonate, probably by
precipitating carbonate ions and driving off carbon dioxide.
Description:
------------
Add a solution of silver nitrate to a solution of sodium bicarbonate: Formation
of a light yellow precipitate and formation of a small amount of a colorless
gas (this probably is CO2). After 10 minutes the precipitate has become
brighter, it has a stronger yellow color, resembling the color of sulphur.
