Titration and Redox Reactions

Flashcards covering key terms and concepts related to titration and redox reactions.

Titration is a technique used to determine the concentration of a substance () in a solution.

analyte

The solution of known concentration that is added to the analyte during titration is called __.

titrant

The __ is the point in a titration where the reaction between the analyte and titrant is complete.

endpoint

The __ in a titration is where the stoichiometrically equivalent amounts of the analyte and titrant have reacted.

equivalence point

Molarity (M) is a measure of concentration expressed as __ of solute per liter of solution.

moles

A __ Titration is based on redox reactions, where the transfer of electrons determines the endpoint.

redox

Quantitative Analysis is the determination of the amount or concentration of a substance in a __.

sample

An Excess Reactant is a reactant present in an amount __ than required by the reaction stoichiometry.

greater

Oxidation is the process in which an element’s oxidation number is increased by loss of __.

electrons

The __ (also, oxidation state) is the charge each atom of an element would have in a compound if the compound were ionic.

oxidation number

An Oxidizing Agent (also, oxidant) is a substance that brings about the oxidation of another substance and, in the process, becomes __.

reduced

A Reducing Agent (also, reductant) is a substance that brings about the reduction of another substance and, in the process, becomes __.

oxidized

Reduction is the process in which an element’s oxidation number is __ by a gain of electrons.

decreased

Stoichiometry refers to the relationships between the amounts of __ and products of a chemical reaction.

reactants

Titration Analysis is a quantitative chemical analysis method that involves measuring the volume of a reactant solution required to completely __ with the analyte in a sample.
