ABSTRACT

"Microscaling" means reducing the mass of chemicals and the volume of the apparatus to an extent that does not compromise the results. At school level, "microscale" comprises the volume range between 5 milliliters and 5 microliters (~ 1 drop from a syringe with smallest blunted needle). In this article, we present some experiments such as electrolysis, redox reaction, and acid-base neutralization, using very small amounts of chemicals.
