Which of the following is a secondary cell?

Electrolysis of the sodium salt of which of the following acids will give ethylene ?

Assertion: KCl is not used in the salt bridge of a cell containign Ag_(aq)^(+) . Reason: Salt bridge contains a saturated solution of an inert electrolyte like KCl, KNO_(3) or NH_(4)NO_(3) in agar -agar.

If in a galvanic cell say, Daniel cell, an inert platinum is used instead of a salt bridge, wil the cell they still produce a potential.

Reagent(s) which can be used to bring about the following transformation is (are) :
