The Fe content in a water sample from a well was determined by subjecting an aliquot of 25.00mL of sample to treatment with HNO3, excess SCN- and finally a dilution of the treated solution to 50.00ml with distilled water. A 10.00mL aliquot of a 5.97 x 10-4M Fe3 + solution was treated in the same way. It was observed that the color of both solutions was the same when the optical path of the standard solution was 3.04cm and that of the well water sample was 2.61cm. Determine the ppm of Fe in the well water sample.

It is required to know the concentration of an aqueous solution of H2SO4 that appeared in the laboratoryChemistry III and it's unlabeled. To this end, a student of analytical chemistry carried out the followingProcedure: He took 5.00 mL of a fresh and standardized solution of 0.525M NaOH and brought them to a250.0 mL balloon to be completed with distilled water. Subsequently, he poured 15.00 mL of the solutionH2SO4 of unknown concentration in an Erlenmeyer flask and added 2 drops of phenolphthalein.Using a burette filled with the last NaOH solution, he noticed that when adding 39.40 mL of the hydroxidethe Erlenmeyer solution reached a faint but permanent pink. With the above dataDetermine the concentration and pH of the H2SO4 solution.

Q: The concentration of the sulphate ion in a mineral water can be determinedby the turbidity which results from the addition of excess BaCl2, to a quantityof measured sample. A turbidometer used for this analysis has been standardisedwith a series of standard solutions of NaSO4. The following resultswere obtained:Standard solution Conc.
