Identify the incorrect statement about \(\mathrm{SiO}_2\) (silica) from the following.
- A It is highly reactive due to low \(\mathrm{Si}-\mathrm{O}\) bond enthalpy.
- B It is a covalent three-dimensional network solid.
- C Quartz, the crystalline form of silica, is used as a piezoelectric material.
- D An amorphous form of silica is used in filtration plants.
Answer & Solution
Correct Answer
(A) It is highly reactive due to low \(\mathrm{Si}-\mathrm{O}\) bond enthalpy.
Step-by-step Solution
Detailed explanation
\(\mathrm{SiO}_2\) is a covalent three dimensional network solid. Silica (commonly known as quartz) is \(\mathrm{SiO}_2\) which is usually used to manufacture glass, ceramics, piezoelectric materials. Most common use of silica is in water filtration, because of its uniform shape…
