Unit 1 Module 2 Test (MC+M) Identify the technique you would use to separate sand from water. Chromatography Filtration Distillation Crystallization

## Step 1<br />The problem is asking us to identify the technique that would be used to separate sand from water. The options provided are filtration, distillation, and crystallization.<br /><br />## Step 2<br />Chromatography is a technique used to separate different components of a mixture based on their different affinities for a stationary phase and a mobile phase. This technique is not suitable for separating sand from water because sand is insoluble in water and does not interact with the water molecules.<br /><br />## Step 3<br />Distillation is a technique used to separate liquids based on their different boiling points. This technique is not suitable for separating sand from water because sand does not boil and does not have a boiling point.<br /><br />## Step 4<br />Crystallization is a technique used to separate solids from solutions by forming crystals. This technique is not suitable for separating sand from water because sand is insoluble in water and does not.<br /><br />## Step 5<br />Filtration is a technique used to separate solids from liquids by passing the mixture through a filter. This technique is suitable for separating sand from water because sand is insoluble in water and can be trapped by the filter paper, while water can pass through.
