Concept explainers
(a)
Interpretation:
The complete balanced equation for the given reaction and the mass percent of oxalic acid has to be found.
Concept Introduction:
Titration is a widely used method for the determination of unknown concentration of an analyte. In order to determine the unknown concentration, the analyte of known volume is titrated with the titrant of known volume and concentration. The unknown concentration of the analyte is found by the following equation.
Where,
This formula is applicable when one mole of analyte is reacting with one mole of the titrant.
After calculating the unknown concentration of the analyte, its weight is gram is calculated.
Mole is the amount of substance having
Mass percent is the one method that is used to express the concentration of substances in a mixture. It is the ratio of weight of a particular component to the total weight of the sample, multiplied by 100.
