Question:
100 cm³ of a given sample of H₂O₂ gives 1000 cm³ of O₂ at S.T.P. The given sample is:
10
10 volume H₂O₂
90
100 volume H₂O₂
Solution:
The correct option is 10 volume H₂O₂.
2H₂O₂ → 2H₂O + O₂
100 ml → 1000 ml
or, 1 ml of H₂O₂ will give 10 ml of O₂ at S.T.P.
Thus, its volume strength is 10 volume.
