12 Questions
What is the term for the point in titration where the amount of standard is equal to the amount of analyte?
Equivalence point
Why are secondary standards used in titration?
Because few compounds can meet the criteria for primary standards
What is the primary standard in titration?
A purified compound that is used as a reference
What is the ideal property of a standard solution for titrometric analysis?
It is stable and reacts rapidly with the analyte
What is the main purpose of back titration?
To add an excess of the standard solution and then determine the excess amount
What is calculated by dividing the mass of a substance by its molar mass?
Amount of moles
What is the most important characteristic of a substance to be used as a primary standard?
High purity
What is the difference between molar concentration and normal concentration?
Molar concentration is the number of moles of reagent, while normal concentration is the number of equivalents of reagent
What is the difference between volumetric and coulometric titration?
Volumetric titration measures the volume of the analyte, while coulometric titration measures the quantity of charge
What is the endpoint in a titration reaction?
The physical change that denotes chemical equivalence
What is the purpose of a standard solution in titrometric analysis?
To determine the concentration of the analyte
What is the purpose of a standard solution in titration?
To react with the analyte to determine its concentration
