an equation for a reaction in solution, where strong electrolytes are written as ions, showing only those components that are directly involved in the chemical change
net ionic equation
a substance that produces hydroxide ions in aqueous solution, a proton acceptor
an acid-base reaction
neutralization reaction
a process involving titration of one solution with another
volumetric analysis
a technique in which one solution is used to analyze another

a chemical that changes color an is used to mark the end point of a titration
the point in a titration at which the indicator changes color
a reaction in which one or more electrons are transferred
oxidation-reduction (redox) reaction
a concept that provides a way to keep track of electrons in oxidation-reduction reactions according to certain rules
oxidation state
an increase in oxidation state (a loss of electrons)
a decrease in oxidation state (a gain of electrons)
a reactant that accepts electrons from another reactant
oxidizing agent (electron acceptor)
a reactant that donates electrons to another substance to reduce the oxidation state of its atoms
reducing agent (electron donor)
the two parts of an oxidation-reduction reaction, one representing oxidation, the other reduction
