Filtration is used to separate a solid from a liquid using a filter. The solid dissolves in the liquid and it also cannot pass through the holes in the filter paper, but the liquid can.

Final answer:

The statement is false because filtration separates an undissolved solid from a liquid; dissolved solids pass through the filter along with the liquid.

Step-by-step explanation:

The statement in question is false. Filtration is used to separate a solid from a liquid in a heterogeneous mixture, where the solid does not dissolve in the liquid. An example of this would be sand mixed with water. When a mixture like this is filtered, the water (the liquid) passes through the filter paper but the sand (the solid) does not, because it is not dissolved and is too large to pass through the pores of the filter paper. Filtrate is the term used for the liquid that manages to pass through the filter. Dissolved solids, like salt (NaCl) in water, cannot be separated by filtration, as they pass through the filter with the liquid. Instead, other methods such as distillation would be required to separate a dissolved substance from the liquid.
