Allows dissolving of cmpds
Back
Reduction
Front
gain of electrons (number decreases)
Back
non-electrolyte
Front
a substance that does not readily ionize when dissolved or melted and is a poor conductor of electricity. Ex : C2H5OH
Back
strong electrolyte
Front
all or nearly all of the solute exists as ions
Back
weak electrolyte
Front
any compound whose dilute aqueous solutions conduct electricity poorly; this is due to the presence of a small amount of the dissolved compound in the form of ions

oxidizing agent
Front
The electron acceptor in a redox reaction. (Cmpds)

Hydration/Solvation
Front
Solvation, is the process of attraction and association of molecules of a solvent with molecules or ions of a solute. Hydration is the process of attraction and association of molecules of water with molecules or ions of a solute.
