Find the volume strength of 1.6 N H2O2 solution. |
|
Answer» We know that strength = Normality × Eq. wt; and Eq. wt of H2O2 = 17 Strength of 1.6 N H2O2 solution = 16 × 17 g/1 Now 68 g of H2O2 gives 22400 ml O2 at NTP 16 × 17 g of H2O2 will give \(\frac{22400}{68}\) × 1.6 × 17 = 8960 ml of O2 at NTP But 1.6 × 17 g of H2O2 are present in 1000 ml of H2O2 solution Hence 1000 ml of H2O2 solution gives 8960 ml of O2 at STP 1ml of H2O2 solution will give = \(\frac{8960}{1000}\) = 8.96 ml of O2 at NTP Hence the volume strength of 1.6N H2O2 solution = 8.96 volume |
