Find the volume strength of 1.6N NH2O2 solution. |
Answer» Strength = Normality × Eq. wt. Eq. wt. of H2O2 = 17 ∴ Strength of 1.6 NH2O2 solution = 1.6 × 17gL-1 Now 68g of H2O2 gives 22400 mL O2 at NTP/STP ∴ 1.6 × 17g of H2O2 will give = \(\frac{22400}{68}\) × l.6 × 17 = 8960 mL of O2 at STP But 1.6 × 17g of H2O2 are present in 1000 mL of H2O2 solution. Hence 1000 mL of H2O2 solution gives 8960 mL of O2 at STP 1 mL of H2O2 will give = 8.96 mL of O2 at STP Hence the volume strength of 1.6 N H2O2 solution is = 8.96 volume. |
