Buffers are made from a weak acid and its conjugate base or a weak base and its conjugate acid. HClO (hypochlorous acid) and NaClO (sodium hypochlorite) form a pair where HClO is a weak acid, but NaClO is the salt of its conjugate base. However, HClO is mistakenly represented with additional symbols and numbers, suggesting a misunderstanding in the chemical representation, making this combination not suitable as described.
