A) \[{{H}_{2}}S{{O}_{4}}\]
B) \[HN{{O}_{3}}\]
C) \[HF\]
D) \[HCl\]
Correct Answer: C
Solution :
\[\text{Si}{{\text{O}}_{\text{2}}}\text{.}\] is soluble in HF only. Therefore/HP cannot be stored in glass or silica bottles as it attack silicates as well as silica. \[N{{a}_{2}}Si{{O}_{3}}+6HF\xrightarrow{{}}N{{a}_{2}}Si{{F}_{6}}+3{{H}_{2}}O\] \[CaSi{{O}_{3}}+6HF\xrightarrow{{}}CaSi{{F}_{6}}+3{{H}_{2}}O\] \[Si{{O}_{2}}+4HF\xrightarrow{{}}Si{{F}_{4}}+2{{H}_{2}}O\] This action of HF on silica and silicates is used for etching glass.You need to login to perform this action.
