Which one of the following statements about hydrogen is wrong? A. Air and pure hydrogen mixture explodes spontaneously

Question

B. Hydrogen does not support combustion although it’s a good fuel C. water is the oxide of hydrogen only
D. 100% pure hydrogen gives a ‘pop’ sound with a burning splin

Answer 1

The statement that is wrong is:

B. Hydrogen does not support combustion although it’s a good fuel

Hydrogen is indeed a good fuel and does support combustion; it burns in the presence of oxygen to produce water. The other statements are either true or have elements of truth:

• A. Air and pure hydrogen mixture can indeed explode if mixed in the right proportions and ignited.
• C. Water is indeed the oxide of hydrogen, and it is the most common oxide formed.
• D. 100% pure hydrogen, when ignited, will produce a characteristic 'pop' sound when a burning splint is introduced, indicating the presence of hydrogen gas.

Therefore, Option B is the incorrect statement.
