Question

Which ion pair would result in the smallest junction potential when used in a salt bridge: $$Na^{+}/Cl$$^{-}$$, K$$^{+}$$/Cl^{-}$$, or $$Li^{+}$/Br^{-}$$? Justify your choice.

Accepted Answer

$$K^{+}$/Cl^{-}$$ because they have similar mobility values, minimizing potential differences.

Answer

$$Na^{+}$/Cl^{-}$$ because they are commonly used in salt bridges.

Answer

$$Li^{+}$/Br^{-}$$ because they have the largest size difference.

Answer

$$Na^{+}$/Cl^{-}$$ because they are both small ions.
