Elizabeth Kidd · Answer 1

- HOCl and NaCl.

- NH4Cl and NaOH.

Explanation:

Hello,

Considering that a buffered solution may contain a weak acid and its salt or a weak base and its salt, the following combinations can not produce a buffer:

- HOCl and NaCl because the salt should be NaClO (sodium hypochlorite).

- NH4Cl and NaOH because the base should be NH4OH (ammonium hydroxide) or the salt NaCl (sodium chloride).

Best regards.
