Test: Hydrogen Peroxide (Old NCERT) - Question 1

What is the chemical formula of hydrogen peroxide?

Detailed Solution for Test: Hydrogen Peroxide (Old NCERT) - Question 1

Hydrogen peroxide’s chemical formula is H2O2 and it was discovered by J.L. Thenard in 1818. It is an important compound used in the treatment of pollution control treatment of Industrial and domestic effluents.

Test: Hydrogen Peroxide (Old NCERT) - Question 2

What is molarity in terms of volume strength of hydrogen peroxide?

Detailed Solution for Test: Hydrogen Peroxide (Old NCERT) - Question 2

The volume strength of hydrogen peroxide is 11.2 times of molarity, which is mathematically represented by X = 11.2 M; where X is the volume strength of hydrogen peroxide and M is the molarity.

Test: Hydrogen Peroxide (Old NCERT) - Question 3

In which of the following, is hydrogen peroxide not stored?

Detailed Solution for Test: Hydrogen Peroxide (Old NCERT) - Question 3

Hydrogen peroxide, represented by H2O2, is stored in acetanilide or sodium pyrophosphate, the presence of traces of alcohol, which slows down the rate of decomposition of hydrogen peroxide (H2O2).

Test: Hydrogen Peroxide (Old NCERT) - Question 4

Hydrogen peroxide is ______________ in nature.

Detailed Solution for Test: Hydrogen Peroxide (Old NCERT) - Question 4

One of the most important chemical properties of hydrogen peroxide i.e. H2O2 is that it is acidic in nature. It is weakly acidic in nature and pure hydrogen peroxide turns blue Litmus red (an indication of acidic nature).

Test: Hydrogen Peroxide (Old NCERT) - Question 5

Hydrogen peroxide is a ______________

Detailed Solution for Test: Hydrogen Peroxide (Old NCERT) - Question 5

Hydrogen peroxide, whose chemical formula is given by H2O2, acts as an oxidizing agent as well as a reducing agent in both acidic and basic medium also. Hydrogen peroxide is an amphoteric substance.

Test: Hydrogen Peroxide (Old NCERT) - Question 6

What does hydrogen peroxide liberate from potassium iodide?

Detailed Solution for Test: Hydrogen Peroxide (Old NCERT) - Question 6

When 2 moles of potassium iodide are reacted with 1 mole of hydrogen peroxide, 2 moles of potassium hydroxide and one mole of iodine is liberated. That means hydrogen peroxide liberates iodine from acidified potassium iodide.

Test: Hydrogen Peroxide (Old NCERT) - Question 7

What is 30% of hydrogen peroxide called?

Detailed Solution for Test: Hydrogen Peroxide (Old NCERT) - Question 7

30% of hydrogen peroxide is called Perhydrol, which is used as an antiseptic and germicide for washing wounds, teeth, and ears. The volume strength of Perhydrol is hundred and its molarity is given by 8.8

Test: Hydrogen Peroxide (Old NCERT) - Question 8

90% of hydrogen peroxide is used as fuel in ______________

Detailed Solution for Test: Hydrogen Peroxide (Old NCERT) - Question 8

Hydrogen peroxide has many uses one of the most important uses of hydrogen peroxide is that it acts as a source of power i.e. 90% of hydrogen peroxide is used as fuel and submarines, rockets and helicopters.

Test: Hydrogen Peroxide (Old NCERT) - Question 9

Which of the following is not a use of hydrogen peroxide?

Detailed Solution for Test: Hydrogen Peroxide (Old NCERT) - Question 9

Hydrogen peroxide is used as a bleaching agent, disinfectant, source of power, in the restoration of old paintings in which lead oxide is used as a white paint, antiseptic and germicide. It is not used in teardrops.

Test: Hydrogen Peroxide (Old NCERT) - Question 10

What is the acute angle between oxygen and hydrogen in the solid form of hydrogen peroxide?

Detailed Solution for Test: Hydrogen Peroxide (Old NCERT) - Question 10

In the solid form of hydrogen peroxide, the angle between oxygen and hydrogen is 104.9 and the angle between the two planes is 92.5. In the liquid or gaseous form of hydrogen peroxide, the angle between oxygen and hydrogen as 94.8 and the angle between the two planes is 111.5

Test: Hydrogen Peroxide (Old NCERT) - Question 11

Normality of hydrogen peroxide is given by 2 and what is its volume strength?

Detailed Solution for Test: Hydrogen Peroxide (Old NCERT) - Question 11

The relation between the volume strength of the hydrogen peroxide and normality is given by X = 5.6 x N, therefore volume strength = 5.6 multiplied by 2N. The volume strength of the hydrogen peroxide is given by 11.2

Test: Hydrogen Peroxide (Old NCERT) - Question 12

Which of the following is the relation between percent strength and volume strength of hydrogen peroxide?

Detailed Solution for Test: Hydrogen Peroxide (Old NCERT) - Question 12

The relation between percentage strength and volume strength of hydrogen peroxide is given by 56 times of percent strength is equal to 17 times of volume strength, which is mathematically represented by; %strength = 17/ 56 X volume strength.

Test: Hydrogen Peroxide (Old NCERT) - Question 13

What is a solution of hydrogen peroxide generally labeled as?

Detailed Solution for Test: Hydrogen Peroxide (Old NCERT) - Question 13

Generally a solution of hydrogen peroxide is labeled as 10volume, which actually means that 1 ml of such a solution of hydrogen peroxide on decomposition by heat produces 10 ml of oxygen at NTP.

Test: Hydrogen Peroxide (Old NCERT) - Question 14
