22. Using the data in the table, write the reaction equations used in the analysis and calculate:
a) the size of the sample for analysis (d);
b) amount of precipitant (ml);
c) the value of the analytical factor (conversion factor);
d) the content of the analyte in the analyzed object (g or %).

Analyzed object analyte substance Analysis scheme Precipitator Weight of weighed form, g Precipitated form of sediment
Technical barium chloride containing about 15% impurities Ba Ba→BaSO4→BaSO4 1M sulfuric acid solution 0.4823 crystalline
