Undissolved

Existing in a solid form within a liquid or other solvent, not having been broken down or absorbed into a solution. This state implies a lack of chemical or physical change that would result in the substance becoming part of the solvent mixture. The substance remains distinct and separate, often visible as particles or pieces, retaining its original properties. This lack of dissolving can be due to factors like insufficient solvent, the insolubility of the substance, or insufficient time for the process to occur. It is often contrasted with words like 'dissolved', 'soluble', or 'homogeneous.

Undissolved meaning with examples

• The scientist carefully observed the beaker, noting the presence of undissolved salt crystals at the bottom. Despite diligent stirring and plenty of water, the solution had reached its saturation point. Adding more salt was futile, as it would simply remain undissolved, affecting the overall clarity and composition of the aqueous mixture. Proper saturation points are important in chemical mixing for clarity.
• During the brewing process, small particles of undissolved coffee grounds remained in the French press after pouring the hot water, detracting slightly from the smoothness of the resulting coffee. They are an important part of the brewing process, but are undesirable in the final drink if consumed. The finest grind possible helps to make it where as much coffee as possible dissolves.
• In the analysis of the contaminated water sample, undissolved sediment was separated and examined to determine the source of pollution. Identifying undissolved particles can lead to discovering the original source of the contamination and is a key component of water treatment.
• When preparing the sugar syrup for the dessert, the cook noted some undissolved sugar granules at the bottom of the pan even after prolonged heating and stirring. Some recipes are highly temperature and mixture dependent. It was important to make sure all the sugar was dissolved for optimal results.
