Hydrogen peroxide (H_2 O_2) was first prepared by Thenard by acidifying barium peroxide and removal of excess water by evaporation under reduced pressure. Its strength can be expressed as weigth percentage or as volume percentage . 25% solution by weight means 25 g of hydrogen peroxide are present in 100 g of solution and 25 volume of hydrogen peroxide means that 1 litre of this solution will give 25 L of oxygen at NTP. Why can dilute solution of hydrogen peroxide not be concentrated by heating ?

Can we use anhydrous barium peroxide for the preparation of H_2 O_2 ?
