A student adds 5 g each of sand, sugar, and salt to 50mL of water. Did he make a solution? Explain

Yes, the student made a solution by adding the sand, sugar, and salt to the water. A solution is a homogeneous mixture where one substance (solute) is dissolved in another substance (solvent) to form a single phase. In this case, the water acts as the solvent, and the sand, sugar, and salt are the solutes. When the solutes are added to the water, they dissolve and distribute evenly throughout the water, resulting in a mixture that is uniform in composition and properties. Therefore, the student has created a solution by adding the sand, sugar, and salt to the water.

To determine if a solution has been made, we need to understand what a solution is. A solution is a homogeneous mixture where one or more substances (called solutes) are dissolved in a solvent, resulting in a uniform composition throughout.

In this case, we have a student who added 5 g each of sand, sugar, and salt to 50 mL of water. Let's analyze each substance individually:

1. Sand: Sand does not dissolve in water. It is insoluble and will remain as a separate phase or sediment.

2. Sugar: Sugar is soluble in water. When sugar is added to water and stirred, it dissolves and becomes uniformly distributed in the water, resulting in a clear solution.

3. Salt: Salt is also soluble in water. When salt is added to water and stirred, it dissolves and becomes uniformly distributed, resulting in a clear solution.

Based on this analysis, the student has made a solution with sugar and salt, but not with sand. So, the mixture would consist of a clear solution of sugar and salt dissolved in water, along with undissolved sand particles at the bottom.

Depending upon how you look at it yes and or no.

Sugar an salt will dissolve in the water but sand will not. It is not a solution of the whole but two of the components are soluble.
