A hair–bleach solution contains H 2 O 2 . The amount of H 2 O 2 in a 12.5 g sample was determined by titration with KMnO 4 in acidic solution. If 39.3 ml of 0.5045 N KMnO 4 was required, how many milligrams of H 2 O 2 are contained in the solution ?
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
0337
Sol. Equivalent of H 2 O 2 = equivalent of MnO – 4
= 
= 0.0198
= 0.0198 × 17 g = 337 mg
