10ml of h2o2 solution react with ki solution to produce 0.5g of iodine. Calculate percentage purity....H2O2+2KI gives 2KOH+I2

Question

Arun · Answer

Write the balanced eqn. first, H2O2 + 2 KI ------------------> I2 + K2O + H2O moles of I2 = 0.5/254 = 0.00196 from mole analysis, moles of H2O2 would be: 0.00196 mass of H2O2 = 0.00196*34 = 0.066929 gm. % purity = 0.066929/10 * 100 = 0.66929 %
