Is the dissolution of borax in water a temperature dependent reaction or is it spontaneous at all temperatures at which water is liquid?
I think its spontaneous at all temperatures when water is liquid because borax is a polar compound.
ethanol is nonpolar while DNA is polar and in the saying "like disolves like" the same applies here. So DNA is soluble in water because it is polar.
sorry but I posted the answer to another question here above.
an answer to your question Danny is that it is temperature dependent since I looked it up and the
0 deg C => 1.99 % by weight in sat solution
100deg C=> 65.64# by weight in sat solution
I'm not sure how to answer your question. Borax dissolves in water; however, the solubility varies with temperature.
so its not spontaneous at room temperature?
the word "spontaneous" would imply that it spontaneously soluble at room temperature but you need a solvent such as water.To me it doesn't make sense to say it's "spontaneous"ly soluble at room temperature.
(saying something spontaneously combusts is the way I would use the word spontaneous but I don't feel it is applicable to a rxn of dissolving borax)
