Answer & Solution
Correct Answer
(B) Both (A) and (R) are correct and (R) is not the correct explanation of (A)
Step-by-step Solution
Detailed explanation
In laboratory, HCl is prepared by heating sodium chloride with concentrated sulphuric acid. NaCl + H2SO4→420K NaHSO4+HCl NaHSO4 + NaCl →823K Na2SO4+HCl HCl gas can be dried by passing through concentrated sulphuric…
