Question

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

• A. not a buffer solution with pH < 7
• B. not a buffer solution with pH > 7
• C. a buffer solution with pH < 7
• D. a buffer solution with pH > 7

Answer 1

The correct option is A not a buffer solution with pH < 7

A buffer is solution of weak acid and its salt with strong base and vice versa.
HCl is strong acid and NaCl is its salt with strong base.
pH is less than 7 due to HCl.
