A) \[N{{a}_{2}}C{{O}_{3}}\] and \[4.81\text{ }g\]
B) \[3.24\text{ }g\]
C) \[1.06\text{ }g\]
D) \[2.03\text{ }g\]
Correct Answer: C
Solution :
Most common component of glass is sodium silicate \[{{\Delta }_{O}}(III)<{{\Delta }_{O}}(II)<{{\Delta }_{O}}(I)\]. HF reacts with it to form sodium fluorosilicate \[{{\Delta }_{O}}(II)<{{\Delta }_{O}}(I)<{{\Delta }_{O}}(III)\]
