Question

6.20 mL of tap water sample is taken in a conical flask and 1 mL of
pH 10 buffer and 3 drops of iochrome black-T indicator are added
and when titrated with 0.001 M EDTA solution, 16 mL EDTA is spent,
so the hardness of the water is determined by French Hardness and
German Hardness Calculate in terms.

5. In an experiment to quantify an unknown amount of FeS04
sample, 0.1 M KMN04 solution was prepared in the first step. Then,
0.216 g H2C204 acid was added to a 250 mL flask, dissolved in 50
mL deionized water and 5 drops of concentrated sulfuric acid was
added. The mixture in the flask was heated up to 70 oC and titrated
with KMN04, which was prepared as 0.1 M. The turning point was
observed when 12 mL of KMN04 was consumed in the titration
process. In the second step, the sample is placed in a 250 mL flask
and dissolved in 50 mL of deionized water. Calculate the amount of
FeS04 in the sample since 25 mL of KMN04 is consumed when 5
mL of sül diluted sulfuric acid is added and titrated with a regulated
KMN04 solution.
