  • Gravimetric Analysis
    A quantitative method using the mass of a solid product to determine the amount of a specific analyte in a sample.
  • Precipitate
    A solid formed from a chemical reaction in solution, separated for measurement to analyze composition.
  • Analyte
    The substance in a sample whose quantity or concentration is being determined through chemical analysis.
  • Molarity
    A concentration unit expressing moles of solute per liter of solution, crucial for quantitative calculations.
  • Stoichiometry
    The calculation of reactant and product quantities based on balanced chemical equations in a reaction.
  • Balanced Chemical Equation
    A symbolic representation ensuring equal numbers of each atom on both sides, guiding quantitative analysis.
  • Atomic Mass
    The weighted average mass of an element's atoms, used to convert between grams and moles in calculations.
  • Significant Figures
    Digits in a measurement that reflect precision, dictating the accuracy of calculated results.
  • Lead(II) Bromide
    A compound formed from lead and bromide ions, whose mass is measured to deduce analyte quantity.
  • Bromide Ion
    A negatively charged bromine species, often the target analyte in precipitation-based determinations.
  • Quantitative Analysis
    A branch of chemistry focused on measuring the exact amount or concentration of substances in a sample.
  • Solution Volume
    The total space occupied by a liquid mixture, typically converted to liters for concentration calculations.
  • Milliliter
    A metric unit of volume equal to one-thousandth of a liter, commonly used in laboratory measurements.
  • Periodic Table
    A systematic arrangement of elements, providing atomic masses essential for stoichiometric computations.
  • Product
    A substance formed as a result of a chemical reaction, whose mass can reveal information about reactants.
