MCQ
Given below are two statements:
Statement I: On passing $HCl _{( g )}$ through a saturated solution of $BaCl _2$,, at room temperature white turbidity appears.
Statement II: When HCl gas is passed through a saturated solution of NaCl, sodium chloride is precipitated due to common ion effect.
In the light of the above statements, choose the most appropriate answer from the options given below:
  • A
    Statement I is correct but Statement II is incorrect
  • B
    Both Statement I and Statement II are incorrect
  • C
    Statement I is incorrect but Statement II is correct
  • D
    Both Statement I and Statement II are correct

Answer

$BaCl _2$, NaCl are soluble but on adding HCl(g) to $BaCl _2$,, NaCl solutions, Sodium or Barium chlorides may precipitate out, as a consequence of the law of mass action.
