Q38.The strength of 11.2 volume solution of H2O2 is [Given that, the molar mass of H = 1 g mol-1 and O = 16 g mol-1] (1) 1.7 % (2) 13.6 % (3) 34 % (4) 3.4 %
What This Question Tests
This question requires converting the volume strength of a hydrogen peroxide solution into its percentage strength using stoichiometric principles.
Concepts Tested
Formulas Used
2H₂O₂(aq) → 2H₂O(l) + O₂(g)
Moles of O₂ = Volume / 22.4 L (at STP)
Percentage strength (w/v) = (Mass of solute / Volume of solution) * 100

Q93.Which of the following chemical reactions depicts the oxidizing behaviour of H2SO4 ? (1) 2HI + H2SO4 ⟶I2 + SO2 + 2H2O (2) Ca(OH)2 + H2SO4 ⟶CaSO4 + 2H2O (3) NaCl + H2SO4 ⟶NaHSO4 + HCl (4) 2PCl5 + H2SO4 ⟶2POCl3 + 2HCl + SO2Cl2
Q64.Amount of oxalic acid present in a solution can be determined by its titration with KMnO4 solution in the presence of H2SO4 . The titration gives unsatisfactory result when carried out in the presence of HCl , because HCl (1) gets oxidised by oxalic acid to chlorine (2) furnishes H+ ions in addition to those from oxalic acid (3) reduces permanganate to Mn2+ (4) oxidises oxalic acid to carbon dioxide and water
