what happens when you mix cream of tartar, baking soda, and water together?
(i've never had time to try this):confused:

KHC4H4O6 + NaHCO3 + H2O = ???

Cream of tartar is KHC4H4O6

I am not asking for formula, I am asking for properties.

Even checking the correct chemical name (not a common name) can give you a hint.

Potassium bitartrate, also known as potassium hydrogen tartrate, has formula KC4H5O6, is a byproduct of winemaking. In cooking it is known as cream of tartar. It is the potassium acid salt of tartaric acid, a carboxylic acid. Also is, according to NIST, used as a primary reference standard for a pH buffer. Using an excess of the salt in water, a saturated solution is created with a pH of 3.557 at 25 °C. Upon dissolution in water, potassium bitartrate will dissociate into acid tartrate, tartrate, and potassium ions. Thus, a saturated solution creates a buffer with standard pH. Before use as a standard, it is recommended that the solution be filtered or decanted between 22 °C and 28 °C.[5]

Potassium carbonate can be made by igniting cream of tartar producing "pearl ash". This process is now obsolete but produced a higher quality (reasonable purity) than "potash" extracted from wood or other plant ashes.

I hope this helps :smile:

It was you who asked the question, so apparently it didn't help as of yet :tongue:

Potassium hydrogen tartrate

or

potassium acid salt of tartaric acid, a carboxylic acid

Both names show it is not fully neutralized acid. It is even enforced by this statement:

saturated solution is created with a pH of 3.557

Low pH, it is an acidic solution.

What kind of reaction could you expect when you mix an acid with a hydrogen carbonate?

umm... it makes CO2 or some other gas? :uhh:.. and fizzes?

No other gas, just CO2 and water. And some fizzing.

Wasn't that hard.
