Question

Find the volume of oxygen at STP produced by 100 ml of 50 V H2O2 on warming?​

Answer 1

Answer:

50 volume means 1L of H2O2 sol'n would produce 50L of oxygen

5H2O2means 1L of H2O2 sol'n would produce > H20 + O2

5 moles of of H2O2 produce 1moles of O2

but 500 H2O2 will produce 50L of oxygen for 1 liter of H2O2

=(50L/24L)moles of oxygen liberated for 1L of H2O2

so in 1L of sol'n of H2O2 moles of H2O2 = 5 moles of oxygen = (5*50/24)=10.42

so n-factor=5

so normality  = molarity*n-factor=10.42*5

        normality=52.1
