unresolved

undissolved
In chemistry, the property of a substance not dissolving in a liquid.
Am Boden des Becherglases blieb ein ungelöster Rest des Pulvers zurück.
An undissolved residue of the powder remained at the bottom of the beaker.
The word consists of the prefix 'un-' (not) and 'gelöst' (solved/dissolved), the past participle of 'lösen' (to solve/dissolve). So it literally means 'not solved' or 'not dissolved'. This fits both a problem that has not been solved and a substance that has not dissolved in a liquid.
Viele mathematische Probleme der Antike sind heute noch ungelöst.
Many mathematical problems from antiquity are still unresolved today.
'Ungelöst' (unresolved/undissolved) belongs to the word family of 'lösen' (to solve/dissolve) and 'die Lösung' (the solution). The verb 'lösen' can mean both 'ein Problem lösen' (to solve a problem) and 'Pulver in Wasser lösen' (to dissolve powder in water), which directly explains the two meanings of 'ungelöst'.
Für dieses Rätsel gibt es keine einfache Lösung.
There is no simple solution to this puzzle.
You can tell from the context whether a problem or a substance is meant. If people are talking about abstract things like a case, a puzzle, or a conflict, the first meaning is intended. In a chemical or physical context, it refers to a substance that has not dissolved.
Der Konflikt zwischen den beiden Ländern blieb ungelöst.
The conflict between the two countries remained unresolved.
In the meaning of 'not clarified', 'ungelöst' (unresolved) is very often combined with nouns such as 'Fall' (case), 'Problem' (problem), 'Rätsel' (puzzle/mystery), or 'Frage' (question).
Die Frage nach dem Sinn des Lebens ist für viele Menschen ungelöst.
The question of the meaning of life remains unresolved for many people.
This meaning of 'ungelöst' (undissolved) is used almost exclusively in the technical language of chemistry or physics to describe the state of a substance in a liquid.
Die Analyse zeigte ungelöste Partikel in der Flüssigkeit.
The analysis showed undissolved particles in the liquid.
open
An open question or decision still needs to be addressed or decided. „Ungelöst“ (unresolved), on the other hand, emphasizes that no solution has yet been found for a problem, puzzle, or question. For a choice that is still pending, „offen“ is often appropriate; after unsuccessful attempts to find a solution, „ungelöst“ is more suitable.
