Solution
The correct separation technique to use in this case would be filtration (d). Here's why:
-
A sand-water mixture is a heterogeneous mixture, which means it contains different substances that remain physically separate.
-
Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered, the sand stays behind in the filter paper (as residue) while the water passes through (as filtrate).
-
The other options are not suitable because: a. Evaporation to dryness: This could also separate the sand from water, but it's not energy efficient as it requires a lot of heat and time. b. Distillation: This is used for
