A compound that acts as both reducing and oxidising agent is-

1. H₂SO₄

2. H₂O₂

3. KOH

4. KMnO₄

The correct statement among the following regarding perhydrol is -

1. It is 30% H₂O₂ or 100 vol. H₂O₂

2. Its molarity is 8.8 M

3. It is used as an antiseptic and a germicide

4. All of the above

OXIDISINThe incorrect statement among the following regarding H₂O₂  is -

${\mathrm{H}}_2{\mathrm{O}}_2$ act as a reducing agent in :

1. Reaction with a ferrous salt.

2. Reaction with iodides.

3. Reaction with lead sulphide.

4. Reaction with ${\mathrm{KMnO}}_4$ in an acid medium.

On bubbling CO₂ through a solution of barium peroxide in water:

1. O₂ is formed

2. H₂CO₃ is formed

3. H₂O₂ is formed

4. H₂ is formed

The reaction of aqueous KMnO₄ with H₂O₂ in acidic condition gives:
1. $M{n}^{4+}$ $and$ $O_2$
2. $M{n}^{2+}$ $and$ $O_2$
3. $M{n}^{2+}$ $and$ $O_3$
4. $M{n}^{4+}$ $and$ $Mn{O}_2$

The correct statement among the following regarding H₂O₂ is-

1. Two hydrogen atoms are connected to one oxygen atom.

2. All the four atoms are in the same plane.

3. The four atoms are arranged in a non-linear and non-planar manner.

4. O-H bonds are polar but the molecule is non-polar.
