Question

2cu⁺ + ni → 2cu + ni²⁺
in the voltaic cell above, which answer choice letter represents the salt bridge?

Explanation:

In a voltaic cell, the salt bridge (containing an electrolyte like \(KNO_3\) here) connects the two half - cells to maintain electrical neutrality. Looking at the diagram, the part labeled \(C\) with \(KNO_3\) is the salt bridge as it is the component that links the two beakers (half - cells) and contains the electrolyte for ion flow.

Answer:

C. \(KNO_3\) (the part labeled C in the diagram)
