Example Of A Reactions That Forms Carbonic Acid, Then Gas: The "Baking Soda Volcano" Page 2

A few more double replacement / exchange examples:

See page 170 for a solubility chart

PRECIPITATION of silver(I)

chloride drives this reaction!

In exchange reactions, transition metal

ions DO NOT change charge!

The FORMATION OF WATER

drives this reaction. It's a

NEUTRALIZATION. Detect by

evolution of HEAT

NO REACTION

NO REACTION occurs There is no DRIVING FORCE, since

both sodium chloride and potassium nitrate are both

soluble ionic compounds, They exist in water as

free ions (just like the original compounds do)

CARBONIC ACID decomposes

under these conditions to

form WATER and CARBON

DIOXIDE GAS (which escapes

as bubbles!)
