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.
