Howarth, O. – Education in Chemistry, 1974
Discusses an experiment which illustrates the non-mixing properties of water at normal temperature with oil because of water's strong, open-ended hydrogen bonding interactions. Examples of the mixing properties between non-interacting substances and the near-complete mixing between water and solvents with limited H-bonding capacity are also given.…
