Is the dissolution of borax in water a temperature dependent reaction or is it spontaneous at all temperatures at which water is liquid?

Question

I think its spontaneous at all temperatures when water is liquid because borax is a polar compound.

Answer 1

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.

Answer 2

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

solubiity
0 deg C => 1.99 % by weight in sat solution

100deg C=> 65.64# by weight in sat solution

Answer 3

I'm not sure how to answer your question. Borax dissolves in water; however, the solubility varies with temperature.

Answer 4

so its not spontaneous at room temperature?

Answer 5

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)
