Answer» Solution :`H_2O_2` cannot be CONCENTRATED by heating because it decomposes much below its boiling point to GIVE `H_2O` and `O_2`. `2H_2O_2 to 2H_2O+ O_2` Therefore, concentrated of `H_2O_2` is carried out in a number of STAGE (i) The `H_2O_2` formed (about 1%) is EXTRACTED with water and the aqucous solution is concentrated by distillation under REDUCED pressure. to give 30% `H_2O_2` solution.
