Could anybody lend me some pointers as to what practical reactions I could do with Calcium Oxide please?
Just looking for perhaps experiments that have some interesting and informative purposes (which I suppose thinking about it all experiments have
that).mineralman - 15-6-2012 at 11:15
make calcium carbonate useing carbon dioxide
make calcium hydroxide
the usual suspects. try googling itweiming1998 - 17-6-2012 at 02:08
CaO is a very useful and strong dehydrating agent. Good for organic reactions that you don't want to get contaminated with water/absorbing water in an
reaction to shift a particular equilibrium forward. An example would be using it to obtain solid pure Na ethoxide via the reaction of NaOH with
ethanol, which is in an equilibrium. (http://en.wikipedia.org/wiki/Sodium_ethoxide). Wikipedia states that the reaction proceeds as: NaOH+C2H5OH<===>NaC2H5O+H2O. Without an
dehydrating agent, a mix of NaOH and ethoxide exists, but the dehydrating agents consumes as product, the water, and shifts the equilibrium to the
right.
Another one would be the on-site generation of Ca(OH)2, which can dissolve in acids to give Ca2+ ions, which might be useful for certain things. A
small amount of Ca(OH)2 could also dissolve in solution and act as a test for CO2. Another would be the reaction of it with carbon at high
temperatures to create CaC2, which reacts with water to form acetylene, a reactive species of hydrocarbon. mineralman - 17-6-2012 at 02:51
ALSO, LOOK IN THE SITES LIBRARY, theres some good stuff in there, theres one with calcium oxide+soil in a contiunous nitric acid electro process IIRC

Thankyou. That last one about calcium ions was useful to know, thanks all.CHRIS25 - 17-6-2012 at 13:20

Hi, did a search for calcium oxide in the search box here but only got about 10 hits, most of them dealing with calcium hydroxide. Does the site have
a reference library then that I do not have access to. I notice that I can not access the references on this site. Is there special status required
for this?
