Determine whether the following statement is true or false:Colloids are the same as suspensions in that particles of one component are suspended in the other component, but in colloids the particles stay suspended.
Question
Determine whether the following statement is true or false:Colloids are the same as suspensions in that particles of one component are suspended in the other component, but in colloids the particles stay suspended.
Solution
To determine whether the statement is true or false, let's break it down step by step:
-
Definition of Colloids: Colloids are mixtures where very small particles of one substance are evenly distributed throughout another substance. The particles in a colloid are larger than those in a solution but smaller than those in a suspension. Importantly, these particles do not settle out upon standing and cannot be separated by ordinary filtration.
-
Definition of Suspensions: Suspensions are heterogeneous mixtures where the particles are large enough to eventually settle out. The particles in a suspension are larger than those in a colloid and can be separated by filtration or decantation.
-
Comparison: Both colloids and suspensions involve particles of one component being dispersed in another. However, the key difference lies in the stability of the dispersion:
- In colloids, the particles remain suspended and do not settle out over time.
- In suspensions, the particles will eventually settle out due to gravity.
-
Statement Analysis: The statement claims that colloids are the same as suspensions in that particles of one component are suspended in the other component, but in colloids, the particles stay suspended.
-
Conclusion: The statement accurately describes the key difference between colloids and suspensions. Therefore, the statement is true.
