A) \[HCl\]
B) \[HBr\]
C) \[HI\]
D) \[HF\]
Correct Answer: D
Solution :
Hydrofluoric acid (HF) reacts with glass sodium and calcium silicate, thus greasy fluorosilicate are formed. This phenomenon is called 'etching of glass', so HF is not stored in glass vessels. \[N{{a}_{2}}Si{{O}_{3}}+6HF\to N{{a}_{2}}Si{{F}_{6}}+3{{H}_{2}}O\] \[C{{a}_{2}}Si{{O}_{3}}+6HF\to CaSi{{F}_{6}}+3{{H}_{2}}O\] Hence, the correct option is (d).You need to login to perform this action.
