In an $\text{H}$ -closed, Urysohn space, disjoint $\text{H}$ -sets can be separated by disjoint open sets. This is not true for an arbitrary H-closed space even if one of the $\text{H}$ -sets is a point. In this paper, we provide a systematic study of those spaces in which disjoint $\text{H}$ -sets can be separated by disjoint open sets.
