MCQ
$1M\ \ce{ NaCl}$ and $1M\ \ce{ HCl }$ are present in an aqueous solution . The solution is :
  • Not a buffer solution with $\ce{pH } < 7$
  • B
    Not a buffer solution with $\ce{pH } > 7$
  • C
    A buffer solution with $\ce{pH } < 7$
  • D
    A buffer solution with $\ce{pH } > 7$

Answer

Correct option: A.
Not a buffer solution with $\ce{pH } < 7$
Buffer can accept and donate protons at the same time and $\ce{HC_1}$ is an acid.
So, it has $\ce{pH } < 7.$
So, this is not a buffer and the solution will be acidic.
