- Prepare 400 mL of a potassium
permanganate aqueous solution, whose molar concentration
equals 1,0.10 mol.L - 1.
- Now make 15 daughter solutions in 15 flasks containing 100 mL,
by taking out of the parent solution :
- flask 1 : 75 mL
- flask 2 : 50 mL
- flask 3 : 40 mL
- flask 4 : 35 mL
- flask 5 : 30 mL
|
- flask 6 : 25 mL
- flask 7 : 20 mL
- flask 8 : 15 mL
- flask 9 : 10 mL
- flask 10 : 8 mL
|
- flask 11 : 6 mL
- flask 12 : 5 mL
- flask 13 : 4 mL
- flask 14 : 3 mL
- flask 15 : 2 mL
