It may then be determined titrimetrically by reduction to the iron II state, and titration with a standard solution of an oxidising agent, such as potassium dichromate or cerium IV sulphate.
Another example that may be mentioned is the determination of the strength of solution of hydrochloric acid both by titration with a standard solution of a strong base and by precipitation and weighing as silver chloride. If the results obtained by the two radically different methods are concordant, it is highly probable that the values are correct within small limits of error. The values obtained for constituents which are present in not too small an amount should not vary among themselves by more than three parts per thousand.
Environmental Pollution and Control, Fourth Edition
Iflarger variations are observed the determinations must be repeated until satisfactory concordance is obtained. Duplicate and at most triplicate, determinations should suffice.
It must be understood that good agreement between duplicate and triplicate determinations does not justify the conclusion that the result is correct; a constant error may be present. The agreement merely shows that the accidental errors, or variations of the determinate errors, are the same, or nearly the same, in the parallel determinations.
If the recovery is satisfactory our confidence in the accuracy of the procedure is enhanced. The method is usually applied to physico-chemical procedures such as spectrophotometry and polarography.
It involves adding a fixed amount of a reference material the internal standard to a series of known concentrations of the material to be measured. The ratios of the physical value absorption or peak size of the internal standard and the series of known concentrations are plotted against the concentration values abscissa.
This should give a straight line.
Any unknown concentration can then be determmned by adding the same quantity of internal standard and finding where the ratio obtained falls on the concentration scale.
In these cases, if the small amount of material can be reacted in such a way that every molecule produces two or more molecules of some other measurable material, the resultant amplification may then bring the quantity to be determined within the scope of the apparatus or method available.
The radioactivity of the isolated material is measured and compared with that of the added element: the weight ofthe element in the sample can then be calculated. It follows, therefore, that systematic errors cause a constant error either too high or too low and thus affect the accuracy of a result. For analytical methods there are two possible ways of determining the accuracy as follows.
Known amounts of a constituent can be obtained by weighing out pure elements or compounds of known stoichiometric composition.
These substances of primary standards, may be available commercially or they may be prepared by the analyst and subjected to rigorous purification by recrystallisation, etc.
The substances must be of known' purity.
Advanced Physical Chemistry, 2/e
The test of the accuracy of the method under consideration is carried out by taking varying amounts of the constituent and proceeding according to specified instructions. The amount of the constituent must be changed because the determinate errors in the procedure may be a function of the amount used.
The difference between the mean of an adequate number of results and the amount of the constituent actually present, usually expressed as parts per thousand, is a measure of the accuracy of the method in the absence of foreign substances. The constituent in question win usually have to be determined in the presence of other substances, and it will, therefore, be necessary to know the effect of these upon the determination. This will require testing the influence of a large number of elements, each in varying amounts.They are due to causes over which, the analyst has no control, and which, in general, are so intangible that they are incapable of y pi analysis.
A Velocity Constant by a Titration Method The second chapter, by A. If a thermostat working at low temperatures is required, then a refrigerating device instead of a heater is used. Dipole Moment of a Polar Molecule The following chapter, on gas equilibria, is very informative and should be useful to anyone interested in the properties of gases.
