Double Displacement Reaction

This reaction (one of my new favorite reactions), is known as a double displacement reaction. This is because 2 reactants mix to form new compounds, exchanging chemicals with each other along the way. For example, calcium chloride (CaCl2) mixes with sodium bicarbonate (NaHCO3). This forms sodium chloride (NaCl), calcium carbonate (CaCO3), water (H2O), and carbon dioxide (CO2). The orange-yellow color comes from the carbonic acid generated when the water mixes with the carbon dioxide. Here's the equation: CaCl2 + 2 NaHCO3 → 2 NaCl + CaCO3 + H2O+ CO2.

sodium bicarbonate is baking soda

[dbc616]

yes it is. And CaCl2 can be found in a household dessicant like "Damp-Rid".

Very informative.

I like it- a great variation on the classic baking soda & vinegar.

Also I like the phenol red it adds a more visible component than just the precipitate, not only that I have over a dozen indicators, but I've never used phenol red.

bitch please...

Can you do the same thing with Sodium carbonate

[hellsascendant]

uh oh in the backround

[physcovideos]

We're doing this in science tomorrow :)

Lol the mess!
