What do scientists use to increase the surface area of a solute?
A mortar and pestle?
Mortars and pestles were the traditional instrument of the apothecary. The male part, the pestle, was used inside the female part, the mortar to grind up a solid and reduce particle size.
In the days before robot chefs, cooks would use mortars and pestles to make, say, pesto for spaghetti sauce.
