Indicator, acid-base
Indicator, acid-base
A substance used in low concentration during a titration that changes color over a certain pH
range. The color change, which occurs as the indicator undergoes a dissociation reaction, is used to
identify the end point of the titration reaction.
Inert gases
Inert gases
The elements located in Group 0 (or Group VIII) of the periodic table. They contain a full octet of
valence electrons in their outermost shell; this electron configuration makes them the least reactive
of the elements. Also called noble gases.
