WebTesting for ions Chris Lloyd 2024-10-21T09:28:56+01:00 An important aspect of school chemistry is the ability to analyse unknown substances. There is a variety of techniques that can be used and, in the case of some organic chemistry, it can get very complicated: looking at melting points IR spectra, NMR spectra etc. WebThe second layer is composed of ions attracted to the surface charge via the Coulomb force, electrically screening the first layer. This second layer is loosely associated with the object. It is made of free ions that move in the fluid under the influence of electric attraction and thermal motion rather than being firmly anchored.
