Which of the following statements is not true for hydrogen peroxide?
(a) Pure H₂O₂ is fairly stable
(b) It sometimes acts as a reducing agent
(c) It acts as an oxidising agent
(d) Aqueous solution of H₂O₂ is weakly basic
Answers
Answer:
Concept:
Hydrogen peroxide (H2O2) is a chemical compound with the formula H2O2. It's a pale blue liquid with a viscosity slightly higher than water in its purest form. It's used as an oxidant, bleaching agent, and antiseptic, commonly as a dilute solution in water for home use and at greater concentrations in industry. Concentrations of hydrogen peroxide, commonly called as "high-test peroxide," breaks down explosively when heated and has been used as a rocket propellant in the past. Hydrogen peroxide is the simplest peroxide, as it is a reactive oxygen species with only one oxygen–oxygen bond. When exposed to light, it decomposes slowly, but quickly in the form of organic or reactive substances.

Answer:
The correct option is (d) Aqueous solution of H₂O₂ is weakly basic
=> It is a very weak acid that is colourless in dilute solutions. It may or may not modify the colour of pH paper, turning it orange red. Because H2O2 is a weak acid, it causes the paper to turn orange red when it comes into contact with it. According to my mentor, water is H2O, which is a neutral compound, while H2O2 is a weak acid. Aqueous solution of hydrogen peroxide containing not less than 20% but not more than 60% hydrogen peroxide (stabilised as needed) appears as a colourless aqueous solution. The eyes and mucous membranes may be irritated by vapours.
