In which of the following solutions the bulb will glows brighter?
Sodium chloride solution is a strong electrolyte and thus complete dissociation will take place. Therefore current flow will be better and the bulb will glow brighter.
On the other hand acetic acid solution is a weak electrolyte and thus it will undergo partial dissociation. Therefore current flow will be not that good and hence bulb glow will be dim.
While since sugar and carbon tetra chloride solution are non-electrolyte and thus they will not ionize.
Therefore no current flow will be there and hence bulb will not glow.
