| May 1, 2019 at 6:05 | comment | added | skwisgaar | @andselisk my field is pretty far from chemistry so I'd really appreciate if you advice some book where this topic is discussed. For now all I could find is that H-bond is responsible for H2O higher melting/boiling point (compared to, e. g. H2S), so, I presume, it keeps molecules together and requires additional energy to break this bond. But I'm not sure how it is connected to mixing with ethanol - maybe it creates bonds with smaller energy or simply breaks some of existing ones in the water, can't find anything definitive | |

| May 1, 2019 at 0:10 | comment | added | skwisgaar | why minus? if you see how to improve the question - let me know, otherwise your downvote is kinda pointless ;) | |
