|Reaction Stoichiometry||The quantitative aspect of chemical reactions; the ratio of substances that are involved within a given chemical reaction.|
|L.1 Mole-to-Mole Predictions Summary||The balanced chemical equation for a reaction is used to set up the mole ratio, a factor that is used to convert the amount of one substance into the amount of another.|
|L.2 Mass-to-Mass Predictions||In a mass-to-mass calculation, convert the given mass into amount in moles, apply the mole-to-mole conversion factor to obtain the amount required, and finally convert amount in moles into mass of the unknown substance.|
| Often between an acid and a base or a reducing agent and an oxidizing agent.|
A solution being analyzed.
A solution of known concentration.
The determination of concentration or amount by measuring volume is called volumetric analysis.
|Stoichiometric Point||The stage at which the volume of titrant added is exactly that required by the stoichiometric relation between titrant and analyte.|
|L.3 Volumetric Analysis Summary||The stoichiometric relation between analyte and titrant species, together with the molarity of the titrant, is used in titrations to determine the molarity of the analyte.|
