Answer
Simple distillation and Crystallisation.
Explanation
## Step 1: Analyse the individual options. Every technique listed here is used to separate components of a mixture, but our target is identifying the correct method for separating a liquid from a dissolved solid. ## Step 2: Filtration is a method used to separate solids from liquids. It typically uses a filter, which allows liquid to go through, but solids get trapped. However, this method does not easily work with a solid that is dissolved in a liquid (the solid could pass through the filter along with the liquid). ## Step 3: Simple distillation is a technique used for separation where components have significantly different boiling points. As here the need is to separate the liquid from a dissolved solid, distillation could serve the principle right as the liquid would vaporize leaving the solid behind.## Step 4:Crystallisation is another method where you dissolve your substance into a hot saturated solution and then let it cool. As the solution cools, the solubility of substances in it decreases. The substance to be purified will crystallize or precipitate out first leaving other impurities still dissolved. It also works well for separating a liquid from a dissolved solid. ## Step 5:Chromatography is typically used for separating components of a mixture, but it serves typically to distinguish different types of solutes within a single mixture (for example, to identify different dyes in an ink sample); it’s not the typical method to separate a liquid from a solid.### So the main formulas which can be used in this context for separation are:1. Filtration: Not highly suitable for dissolved solids. 2. Simple distillation: Suitable for separation of liquid from a dissolved solid. 3. Crystallisation: Highly suited for dissolving solids from a liquid.4. Chromatography: While not commonly used for only liquid-solid separation, can potentially be employed in case of a need.
