# Separating mixtures, sentence 3

<!-- .ven lang=en -->
Dissolved things are harder: salt in water passes through any filter, so you must let the water evaporate to leave the salt behind, or boil it off and catch the steam to get pure water.

<!-- .vintro -->
**Who acts:** Dissolved things, salt, you, water · **What happens:** dissolve, be, pass, let, evaporate, leave · **To what, where:** filter, water, salt, steam, pure water

<!-- .vabout -->
This is a sentence of the lesson «Separating mixtures» of the chemistry course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (Dissolved things, salt, you, water), what happens, when and where, as Mova's frames read it from the tree.
