Vedclass · Answer

(A) mixture of $1 \ M \ NaCl$ and $1 \ M \ HCl$ contains a strong acid $(HCl)$ and its salt with a strong base $(NaCl)$.Since $HCl$ is a strong acid,it dissociates completely to provide a high concentration of $H^+$ ions,resulting in a $pH For a solution to act as a buffer,it must contain a weak acid and its conjugate base,or a weak base and its conjugate acid.Since $HCl$ is a strong acid,this mixture does not resist changes in $pH$ upon the addition of small amounts of acid or base.Therefore,it is not a buffer solution.
