How do you prepare HCl in the laboratory? – InterviewSolution

1.	How do you prepare HCl in the laboratory?
Answer» SOLUTION :`HCl` is PREPARED in the labortory by heating sodium chloride with conc. `H_(2)SO_(4)`. `NaCl+H_(2)SO_(4)overset(420K)rarr NaHSO_(4)+HCl` `NaHSO_(4)+NaCl overset(823K)rarr Na_(2)SO_(4)+HCl` `HCl` gas is dried by PASSING through conc. `H_(2)SO_(4)`.
