A precipitate will be formed through the double displacement method in chemical reactions. The chemical equation would be: Na2CO3 + AgNO3 ----> NaNO3 + Ag2CO3. Balancing would result to: Na2CO3 + 2AgNO3 ----> 2NaNO3 (aq)+ Ag2CO3.
Ag2CO3 is the precipitate formed. It is yellow in color but due to the presence of elemental silver, it is a bit grayish.
