Translated title of the contributionTest your knowledge with challenges from the International ChemistryOlympiad! : Nanoparticles from gold and silver solutions
With surprisingly small amounts of gold and silver solutions, gold and silver nanoparticles in the colors blue, red, and yellow can be produced by chemical reduction with sodium citrate in hot water.
In addition to practical instructions, there are theoretical tasks concerning the topic nanoparticles. The aim of this offer is to motivate for chemistry and to encourage pupils to participate in the ChemistryOlympiad.
