Physical properties 1 - Colorless, odorless and bitter taste liquid. 2 - The boiling

Physical properties 1 - Colorless, odorless and bitter taste liquid. 2 - The boiling point of H 2 O 2 is 150. 2 °C. 3 - It is miscible with water but soluble in ether. 4 - Stable by add small a mounted (H 2 SO 4) and (H 3 PO 4).

Chemical properties 1 - Decomposition into H 2 O and O 2 2 H

Chemical properties 1 - Decomposition into H 2 O and O 2 2 H 2 O 2 2 H 2 O + O 2 2 - Hydrogen peroxide has both oxidant and reductant properties. As oxidizing agent when give oxygen to other compound and H 2 O relapse K+1 N+3 O 2 -4 + H 2 O 2 K+1 N+5 O 3 -6 + H 2 O 2 -2 + 2 e H 2 O-2 Reduction reaction N+3 N+5 + 2 e Oxidation reaction As reducing agent when O 2 relapse Ag 2 O + H 2 O 2 2 Ag + H 2 O + O 2 Ag 2+1 O-2 + 2 e 2 Ag 0 Reduction reaction H 2 O 2 -2 O 20 + 2 e Oxidation reaction

Pharmaceutical application 1 - Use as Hair lightening and has deodorant properties. 2 -Antimicrobial

Pharmaceutical application 1 - Use as Hair lightening and has deodorant properties. 2 -Antimicrobial agent due to liberated (O 2). 3 - Used for disinfecting wounds and ulcers (6%). 4 -Solution (1. 5%) used as mouth wash. 5 -Used for tooth whitening. 6 -It is used as ear- drops for removal of
