A sample of Al2(SO4); weighing 7.52-g was dissolved in enough water and diluted to 250.0-mL. 100.0-mL of the dilution was transferred to another flask, 10.0-mL of 0.050M EDTA, 20-mL of buffer solution, 50-mL of alcohol and 2.0-ml dithizone TS were added. The resulting solution required B.7-mL of 0.031M ZnSO, to reach the endpoint. (Note: Each ml of 0.050M EDTA is equivalent to 16.66-mg Al2(SO.)h•18H;0). Compute for the percent purity of the sample.

A solid containing tris was dissolved in water and brought to a total volume of 50.00 ml. A 10.00 ml aliquot of the solution was titrated with 0.09978 M HCl to a bromcresol green endpoint. The aliquot consumed 38.93 ml of titrant. Calculate the weight of tris in the original sample.
2) The following experimental process steps have been made to determine the hardness of water. Accordingly, 100 mL sample was acidified with a few drops of 6 M HCl and boiled for a while to remove the CO2 in it. Then, a few drops of methyl red (pH: 4.2-6.3) were added to the cooled sample and the solution was neutralized with 0.1M Na0H, then 2 mL of 0.01M pH10 buffer and 4-5 drops of EBT indicator were added and the solution was 0.0086M. It was titrated with EDTA until the color turned blue. Since the consumption of titrant is 11.44mL, calculate the amount of Ca in the water in terms of mg CaСОЗ. (Са: 40, С: 12, 0: 16)
A 1.000 mL aliquot of a solution containing Cu²+ and Ni²+ is treated with 25.00 mL of a 0.04333 M EDTA solution. The solution is then back titrated with 0.02071 M Zn²+ solution at a pH of 5. A volume of 20.01 mL of the Zn²+ solution was needed to reach the xylenol orange end point. A 2.000 mL aliquot of the Cu²+ and Ni²+ solution is fed through an ion-exchange column that retains Ni²+. The Cu²+ that passed through the column is treated with 25.00 mL of 0.04333 M EDTA. This solution required 18.20 mL of 0.02071 M Zn²+ for back titration. The Ni²+ extracted from the column was treated witn 25.00 mL of 0.04333 M EDTA. How many milliliters of 0.02071 M Zn²+ is required for the back titration of the Ni²+ solution? volume: mL
Chemistry A 0.3500 g sample of impure KI is treated with 0.1942g of pure K2CrO4 and the solution is boiled to expel all of the liberated iodine. The cooled solution is then treated with excess KI and the liberated I2 titrated with 0.100N sodium thiosulfate, requiring 10.00ml. Find the percentage purity of the original sample of KI

Finely ground mineral (0.9315 g) was dissolved in 25 mL of boiling 4 M HCl and diluted with 175 mL H2O containing two drops of methyl red indicator. The solution was heated to 100C, and 50 mL of warm solution containing 2.0 g (NH4)2C2O4 were slowly added to precipitate CaC2O4. Then 6 M NH3 was added until the indicator changed from red to yellow, showing that the liquid was neutral or slightly basic. After slow cooling for 1 h, the liquid was decanted and the solid transferred to a filter crucible and washed with cold 0.1 wt% (NH4)2C2O4 solution five times until no Cl- was detected in the filtrate upon addition of AgNO3 solution. The crucible was dried at 105C for 1 h and then at 500 ± 25 C in a furnace for 2 h. Ca2+ + C2O42- --> CaC2O4.H2O(s) -->500C CaCO3(s) The mass of the empty crucible was 16.9743 g, and the mass of the crucible with CaCO3(s) was 17.198164 g.
