Question

1 M NaCl and 1 M HCl are present in an aqueous solution. The solution is :
Answer options :

(a) Not a buffer and its pH< 7
(b) Not a buffer and its pH>7
(c) A buffer with pH < 7
(d) A buffer with pH >7

Answer 1

Buffer = weak acid and its salt. You have a strong acid and its salt.

HCl = strong acid so it dissociates completely; the pH = -Log[H] so it would be less than 7.
