Question
The photo to the right shows a dust storm in Texas in 1935.Identify the two main things being mixed in the storm.Explain whether the mixture is a suspension.
Solution 1
The two main things being mixed in the dust storm are dust particles and air.
A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase some time after their introduction. In the case of a dust storm, the dust particles (solute-like phase) are temporarily mixed with the air (solvent-like phase) due to the high winds. However, once the wind dies down, the dust particles will eventually settle back down onto the ground due to gravity. Therefore, the mixture of dust and air in a dust storm can be considered a suspension.
