**Question:**Which one of the following pairs cannot be mixed together to form a buffer solution?**Options:**- a. HONH₂, HONH₃Cl- b. KOH, HNO₂- c. RbOH, HF- d. NaCl, HCl**Explanation:**A buffer solution typically consists of a weak acid and its conjugate base or a weak base and its conjugate acid. Among the options provided:- Option a consists of a weak base (HONH₂) and its conjugate acid (HONH₃Cl), which can form a buffer.- Option b can form a buffer as it includes a weak acid (HNO₂) with its conjugate base (KOH partially neutralizing the acid).- Option c also involves a weak acid (HF) with a base (RbOH).- Option d, NaCl and HCl, cannot form a buffer solution because HCl is a strong acid, and NaCl is a neutral salt. There is no weak acid or base with its conjugate to maintain a constant pH.Thus, the correct answer is **d. NaCl, HCl**.

Given: A buffer solution can be prepared using: a weak acid and it's conjugate base A weak base and…
