Accuracy - the accuracy of a method is the closeness of the measured value to the true value for the sample
Desiccator - in which dried materials may be stored while they cool to minimize the uptake of moisture
Gravimetric analysis - involves determining the mass of the species being analyzed or the mass of a compound chemically related to that species
Mother liquor - the solution from which a precipitate is precipitated
Permanganate index of water - indicates the amount of permanganate consumed when the oxidizable matter in a water sample is oxidized by the permanganate
Random error - an experimental error which causes measurements to be distributed randomly on either side of the true value. Random error exists in every measurement. We can never eliminate the effect of rando
Redox titration - like an acid-alkaline titration; a similar procedure used to determine the concentration of an oxidizing agent or a reducing agent
Sensitivity - the sensitivity of a method is the ability to distinguish between two different concentrations
Sintered glass filtering crucible - the porous glass bottom of the crucible allows liquid to pass but retains solids for filtering purpose, enabling the filtration, drying and weighing steps to be completed i
Standardize - it is necessary to standardize a solution of the chosen reagent to obtain its accurate concentration prior to its use for titrimetric analysis
Systematic error - an experimental error which arises from a flaw in equipment, operations during the experiment or the design of the experiment. We cannot eliminate such an error by repeating the measurement
Titrant - the reagent of known concentration added to the species being analyzed during titration
Titration - a process which involves measuring the volume of a solution containing sufficient reagent to react completely with the species being analyzed during a volumetric analysis
Volumetric analysis - involves measuring the volume of a solution containing sufficient reagent to react completely with the species being analyzed in a process called titration
