Mortar and Pestle Porcelain
Mortar and Pestle Porcelain
This is used to pulverize/mash/grind and mixes materials in a mortar
using a pestle to demonstrate how particle size affects solubility and
the rate of chemical reaction.
Decreasing the size of the particles increases the rate of dissolving
and speeds up the rate of reaction because the surface area of the
reactant has been increased.
